Puppeteer's Secrets

[Darkenslight]

Conjurer's Puppet Game

Sorcery
Put a 0/1 red Kobold token with haste, a 1/1 red Goblin token with haste, and a 2/1 red Viashino token with haste into play. Remove them from the game at end of turn.
Secretly choose one of them. At end of combat, if the chosen token is attacking and unblocked, you may reveal your choice and draw 3 cards.

It seems only slightly overpowered at the current cost.  I think it might need a little clearing up:

Puppeteer's Secrets
Instant

Play Puppeteer's Secrets only before the declare attackers step.

Could someone explain why you would ever want to use this over Concentrate?

Much thanks for the name.

I think this version could be used in combat on your opponent's turn, too.

Never underestimate the power of a U/R surprise.

Make it playable only on your turn.  That's clearly what is intended by the flavor.

1.  Because this card is much more fun to play than Concentrate.  There are plenty of Izzet madmen out there, such as myself, who enjoy playing cards with potentially powerful, but bizarre or unpredictable effects.

2.  In a given environment, Concentrate may not be available.  A card like this may be a weaker, but more interesting replacement for some of the available card-drawing solutions in an environment.
