I recently acquired a Command Beacon, a Mystic Confluence, and a Mox Diamond. I need to find spots for these, especially the Mox Diamond. Being able to get Tasigur, the Golden Fang out on turn-2 with the help of Tome Scour is all well and good, but the chance to get him out on turn-1 is too good to pass up.

I hate to be that guy, but Tasigur can't be your commander with your current decks colors. You deck can only have cards that are of the same color as your commander.

mebamissle Not entirely true. Color identity includes activated abilities, not just casting cost.

"... the color identity of a card is specified by all mana symbols that appear in its casting cost, color indicator, and rules text. This is primarily relevant for the Commander format, in which players are not allowed to use any cards whose color identity isn't encompassed by that of their General." MTG Salvation, Color Identity

Huh, I didn't know that. Haha, thanks!

I'm currently considering swapping out Think Twice for Spell Pierce. Forbidden Alchemy is potentially on the chopping block; I've yet to cast it for its Flashback cost and I often time find myself wishing for more removal than card draw. It's most likely that Undermine will take its place if I do remove it.

Hooting Mandrills for another big guy?

aves01 Huh! I totally forgot about Hooting Mandrills. Good call. Adding it to the Maybeboard for now, but I think its got a shot.
