Kasmina, Enigmatic Mentor
Legendary Planeswalker — Kasmina
Spells your opponents cast that target a creature or planeswalker you control cost
more to cast.
−2 : Create a 2/2 blue Wizard creature token. Draw a card, then discard a card.
To determine the total cost of an opponent’s spell that targets a creature or planeswalker you control, start with the mana cost or alternative cost that player is paying, add any cost increases (such as that of Kasmina’s effect), then apply any cost reductions. The converted mana cost of the spell remains unchanged, no matter what the total cost to cast it was.
