Creatura — Mago Zombie
2 / 2
Quando l'Alchimista di Sedraxis entra in gioco, se controlli un permanente blu, fai tornare un permanente non terra bersaglio in mano al suo proprietario.
The "intervening 'if' clause" means that (1) the ability won't trigger at all unless you control a permanent of the specified color, and (2) the ability will do nothing unless you control a permanent of the specified color at the time it resolves.
This ability isn't optional. When Sedraxis Alchemist enters, if you control a blue permanent and no other player controls a nonland permanent, you'll have to target a nonland permanent you control.
