GushBond Tendrils

[vassago]

So, this is my initial impression on how stupid GushBond will look. 

Is this lacking? Like should key/vault be there? Should I cut them to make more room for another tendrils and a fifth duress effect?

Do I need top? If so, what should I cut for it? Or should I just play 61(I know this sounds awful)?

Should I have regrowth?

Is the swamp as necessary as I think it is?

Flipping Gush to Bob hurts.

Flipping Gush to Bob hurts.

Not more than FoW!

4 Fow
4 Gush
1 Gifts
1 Tendrils

If you're unlucky enough to draw none of these, you can surely use confidant to grab them!

A first turn bob gives you a 10/53 or 18.8% chance to deal 4 or 5 damage! Woot! Increasing ~0.8% each turn.
10/50 20% to deal damage, 20.4% chance to draw the card without damage.

So I guess top is necessary. Maybe even preordain. I forgot last time I played something similar I could use 4 brainstorm.

I'm no pro on gushbond but it seems Enlightened Tutor doesn't mind a meta with vault key and fastbond.

I'd play Frantic Search over Bob :O

My suggestions:
-1 Mox Pearl
-1 Mana Crypt
-1 Sol Ring
-3 Bob
-1 High Tide
-2 Dark Ritual
-3 Drain
+1 Lotus Petal
+1 Library of Alexandria
+1 Ponder
+4 Lotus Cobra
+1 Regrowth
+1 Mystical Tutor
+2 Preordain
+1 Spell Pierce

With those changes, the deck gets a lot of boosts.

Mostly, you don't want to fry your face with Bob, so he's gone (plus you've lost Brainstorm to combo with him). Then, you don't have a reliable mana-finder (which B-Storm used to be), so added Ponder and 2x Preordain. Also, with all of the 1cc Sorce.ries (discard and ponder/preordains) it's hard to rely on Drain even working, when these should find your Gush and/or FoW more reliably.

Lotus Cobra will generate colored mana over the colorless options the deck has, which I think is vitally important. Also, left the Red Mox because sideboard will probably contain 2 REB (if not other Red cards). Sol Ring and Mana Crypt aren't bad, but aren't great either. Other than Vault-Key, they are very dead (except *maybe* vs Shops). Additional lands would be stronger, and also Library is huge in this matchup for many reasons.

Regrowth is that huge.
