You are playing Infect against Death and Taxes, and you know the opponent has Umezawa’s Jitte in hand.
There are 2 options here, so let’s break them down.
1) Cast Brainstorm (paying 2 because of Thalia).
2) Attack with both Blighted Agent and Glistener Elf.
If the opponent makes the obvious block of Thalia on Glistener Elf, you win. You let first strike damage resolve, Elf dies, and you now have exactly enough mana and cards in graveyard to delve and play Become Immense on Blighted Agent. It’s a tricky play from the opponent’s side, so there’s a good chance it works, but if they block with Stoneforge Mystic instead, you likely lose to Jitte. Time to cross your fingers!
