Permafrost Trap⁣ - Worldwake⁣ (Uncommon)⁣ [34]

Permafrost Trap allows you to tap up to two target creatures for just a single blue mana if an opponent has played a green creature that turn. This can disrupt their combat plans and prevent them from using those creatures effectively in the following turn. It's valuable in control decks that aim to stifle aggressive strategies by limiting the opponent's options.
