I think it's a bit weird to put the counters on the imprinted card. What about:

Imprint - 0: Remove an artifact card in your hand from the game face up, then remove all charge counters from Production Scheduling.

1: Put a charge counter on Production Scheduling.

Remove X charge counters from Production Scheduling: Put the last imprinted card into play. X is the converted mana cost of that card.


Incidentally, the most similar existing card is probably Iceberg...

I thought Chupacabra was the name for man-sized chickenlike creatures.
So shouldn't they be birds? Maybe bird spirits?

Intellectual Property?

Yes, it might get you four lands. But unless you're using something (Scouting Trek) to put them there, it might also fetch no lands and leave you manaless. That's really not very useful.

Er, it sacrifices all your lands? That's ludicrously weak when you could have Nature's Lore or Sakura-Tribe Elder for the same cost.

(If all your lands are forests, maybe you'd find 1 or 2 among the 5 cards you reveal. Obviously you can do better if you combo it with Scouting Trek, but then you're playing 2GG for a 2-card combo that fetches, um, 5 basic forests into play... tapped. I'd rather have Gaea's Balance.)

My version:

Rain of Trees
1G
Sorcery
Sacrifice all non-forest lands you control. Search your library for that many basic forest cards and put them into play.

Exploiting the "non repeating" behaviour of replacement effects:

"If a player would win or lose the game, all his or her opponents do so instead."

Ok, well, clock then.

Playable? Are you serious? It's the kind of card that would get "interviewed about why it's unplayable" on Misetings...

If you're concerned about symmetry, how about upping the cost to 2?

Actually I think these are pretty weak.
You're laundering 1 into a (specific) colored mana on the turn you cast it, and then generating another colored mana the turn after. That's the same amount of acceleration as Elvish Spirit Guide, but it takes an extra turn and you need mana to set it up in the first place.

Consider this version:

Garnet Gemstone
0
Artifact
Garnet Gemstone comes into play tapped.
T, Sacrifice Garnet Gemstone: Add R to your mana pool.

Is that playable? I don't think so. And that's essentially the same card, except you don't get the (weak, possibly inconvenient) mana laundering effect.

I think they should start out with 3 depletion counters, or produce more than one colour.

Sol Shovel?

This looks reasonable. Pretty weak first turn, which of course is the point.

Power-setting effects don't work perfectly, but they're tolerable. (They printed Riptide Mangler not all that long ago, remember). It doesn't matter whether a creature has a power-setting ability, external effects will always override internal ones.

To make it more useful, how about "Target creature's power and toughness become equal to the number of cards in target player's hand"?

Changed to a 2/3 with Vigilance, to recover some of the "can't attack" flavour of the original.

At the moment it only spares creatures that it hasn't already spared; does that seem fair?

And I realise... this creature can't be affected by Kiku, Night's Flower! The first time, he gives himself a counter; after that he's got protection from himself.

Don't you mean

If an opponent would win the game, instead you win the game.
If an opponent would lose the game, instead you lose the game.

The whole point of using counters is so the players don't have to remember exactly which ones have been affected.
What if it changes colour and gets a counter, like Sensei Golden Tail?

Names...

Preternatural Sasquatch feels like a Goblin (do we have goblins in this set?) and the mechanic feels like he's drawing his power from the air or the aether or something.
So I suggest "Goblin Lightning Rod".

Tricky Sasquatch/Balshan Lobster feels like some kind of elemental or illusion... Sublimation Elemental? Vapor Elemental? Vaporous Soldier?

Sentry Sasquatch... Spirit of the Eastern Sky?

At the moment I think this is very very weak. Even a five-colour deck rarely has permanents of each colour in play.

Have you considered making this an artifact creature?

I guess that restricts its usefulness, then.

So, what should it reveal?
How about "Reveal two creature cards with the same name"? That ties in with all the black cards that require multiples.
Or maybe "Reveal a creature card with the same name/type as a creature card in a graveyard"?

I like that. Ok.

I think it would be more elegant if it said:

Rainbow Elemental
1U
Creature -- Elemental
*/*
Flying
Rainbow Elemental's power and toughness are each equal to the number of colors among permanents you control.

So it's a 1/1 flier on its own, or a 2/2 if you control a different coloured permanent. I think that's reasonable for 2 mana, but it would need testing. Perhaps 3 would be a fairer cost.

Sentry Sasquatch is interesting. You probably wanted to add "until end of turn" though.

Alternatively, how about:
Reveal an enchantment card from your hand: Sentry Sasquatch gains protection from black and from red until end of turn.

Evil Sasquatch is completely mental - it's a Hill Giant with the minor ability of being practically unkillable. I think it needs to have (at the very least) a mana cost in addition to the reveal. Or else it needs to have a stricter reveal requirement.

Evil Sasquatch
2BB
Creature - Sasquatch
3/1
B, Reveal a black creature card from your hand: Regenerate Evil Sasquatch.

And how about this idea:

Preternatural Sasquatch
1R
Creature - Sasquatch
1/1
T, Reveal a red card from your hand: Preternatural Sasquatch deals 1 damage to target creature or player.

The problem with the "creature cards" wording is that an animated land is a creature and is a card, but isn't a creature card.
(This distinction made sense when we had "summon cards", but no longer does. That's why this wording is no longer used.)

I suggest:

Essence Sweep
Sorcery
Destroy all creatures except token creatures, artifact creatures, and land creatures.

Merciful Monk
2W
Creature - Cleric
3/3
If Merciful Monk would deal lethal damage to a creature, prevent that damage. Put a life-debt counter on the creature and it gains defender. (It can't attack. This effect doesn't end at end of turn.)

Current wording:

Merciful Monk
2W
Creature - Cleric
2/3
Vigilance, Protection from creatures with grace counters.
If Merciful Monk would deal lethal damage to a creature without a grace counter, prevent that damage and put a grace counter on the creature.

The second ability is a static ability, so when Soulhunter dies, the creatures can regenerate again.

I suggest "Whenever Soulhunter deals damage to a creature, that creature can't regenerate this turn".

Now it's even more similar to Puppeteer!

Good call.

Clock.

More simple blue creatures -

Saprazzan Guillemot
1U
Creature - Bird
2/2
Flying
Play ~ only if you played an island this turn.

Balshan Lobster
4U
Creature - Crustacean
3/3
Reveal an instant card from your hand: Balshan Lobster is unblockable this turn.

Are Iridescent Avizoa and Warrior Owl in the set?

Seems fair. The cost itself isn't much of a disadvantage; the only real one is the need for a dead creature in the first place.
So it's certainly better than Skulltap...
