Seedtime

Hate cards usually do nothing, and trade a card for a small inconvenience. This one inverts the deal entirely: instead of taxing the blue mage or counter-taxing their counters, it punishes them with a free turn. The condition is the whole engine. It can only be cast on your own turn, so it is dead as a reactive spell; the extra turn arrives only if, on resolution, an opponent has cast a blue spell during your turn. A counterspell, a bounce spell, a Fact or Fiction, a removal spell held up at end of step: any of these makes Seedtime live. The blue deck's entire identity is built around acting on your turn, so the card weaponizes the opponent's own reflexes against them. The result is a piece of green-versus-blue technology so pointed it reads almost as a thesis statement: the color of fast mana and big creatures finally gets to tell the color of permission "no, and now I untap, draw, and deploy again before you do anything." An extra turn is among the most powerful effects in the game, and this hands one over for two mana, gated only by the opponent's willingness to interact at instant speed. Against a deck built to play draw-go, the mere knowledge that this is in a list distorts how freely they can hold up answers.
