Yeah that makes Tarmogoyf a pretty bad creature. How does it get turned into Phage, tho?
The worst case for Brainstorm is when your opponent Mindslavers you and uses it to dig for Reanimate, targeting Phage.
meanwhile, phage is just her own floor
It would've been a cute interaction, yeah, but then it would be easy to block. The threat of activation works well and creates a bunch of tension and mindgames.
the problem there is that to play Monosk. and kill a thing, you’re spending 3 mana and leaving behind a 1/1.
so for example, killing Mom or Lavamancer is +0.5 cards of positive VALUE (assuming they haven’t untapped with either one, as these cards generate value each turn they’re tappable), but -1.5 mana of negative TEMPO as they only spent 1 mana to cast the critter that you’re spending 3 mana to kill and make a 1/1.
(these value/tempo numbers are based on my assumption that a 1/1 is worth half a card and half a mana.)
so you’re spending 1 card and 3 mana to go up 1/2 card, down 1.5 mana, and that’s in a FAVORABLE situation for the card. of course you can create MORE favorable scenarios by increasing the cost of the ping target or engineering a blowout, but i feel like this is a fair scenario to use for evaluating how good the card is going to feel to cast. i should note that if the opponent is ahead on board with mid/large creatures, or if you’re in lategame/topdeck style of parity, the card gets much closer to a vanilla 2/2 for 2.
