Guardian of Tazeem | Creature | Sphinx | Flying
Landfall — Whenever a land enters the battlefield under your control, tap target creature an opponent controls. If that land is an Island, that creature doesn't untap during its controller's next untap step. | Zack Stella
Windrider Patrol | Creature | Merfolk Wizard | Flying
Whenever Windrider Patrol deals combat damage to a player, scry 2. (Look at the top two cards of your library, then put any number of them on the bottom of your library and the rest on top in any order.) | Svetlin Velinov
Noyan Dar, Roil Shaper | Legendary Creature | Merfolk Ally | Whenever you cast an instant or sorcery spell, you may put three +1/+1 counters on target land you control. If you do, that land becomes a 0/0 Elemental creature with haste that's still a land. | Karl Kopinski
