At the beginning of your upkeep, put a shield counter on target creature an opponent controls.

Whenever you put one or more counters on a creature you don't control, tap that creature and goad it. It gains trample until your next turn. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)

Flying

At the beginning of combat on your turn, you may pay . When you do, put a +1/+1 counter on another target creature you control, and that creature gains flying until end of turn.

Flying

Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)

At the beginning of combat on your turn, choose up to one target creature you control. Until end of turn, that creature gets +2/+0, gains trample if it's red, and gains vigilance if it's white.

At the beginning of combat on your turn, up to one target land you control becomes an X/X Elemental creature with trample and haste until end of turn, where X is Obuun's power. It's still a land.

Landfall — Whenever a land you control enters, put a +1/+1 counter on target creature.
