Sentinel's Mark

Defender T: Put target card from a graveyard on the bottom of its owner's library.

Creatures you control get +0/+5 and gain reach until end of turn.

Target creature gets +2/+2 until end of turn. Addendum — If you cast this spell during your main phase, that creature gains flying until end of turn.

You can't cast noncreature spells. Whenever you tap a land for mana, add one mana of any type that land produced.

Defender 6G/UG/U: Adapt 3. (If this creature has no +1/+1 counters on it, put three +1/+1 counters on it.) As long as this creature has a +1/+1 counter on it, it can attack as though it didn't have defender.

As an additional cost to cast this spell, sacrifice two creatures. Draw three cards.

Hexproof (This creature can't be the target of spells or abilities your opponents control.)

Flash Flying When this creature enters, target creature an opponent controls gets -2/-0 until end of turn.
