Target creature gets +2/+2 until end of turn. If you cast this spell from exile, that creature gets +4/+4 and gains trample until end of turn instead.
Prophecy {G} (Once each turn, you may exile a card with prophecy as you reveal it. When you do, you may cast it for its prophecy cost as long as it's exiled.)

Destroy up to one target artifact or enchantment. Rouse 2. (Distribute two +1/+1 counters among permanents you control. If they aren't creatures, tap them and they become 0/0 creatures in addition to their other types.)

Whenever a -1/-1 counter is put on a creature, you may create a 1/2 green Frog creature token.

Reveal the top six cards of your library. Put all noncreature cards revealed this way into your graveyard, put the rest back on top in any order, then draw cards equal to the number of cards put on top.

Once each turn, if you would draw a card, you may skip that draw. If you do, create a tapped 3/2 colorless Horror creature token.

Whenever a creature you control enters, if its mana value is greater than the number of bloom counters on From a Seed, put a bloom counter on From a Seed.
Creatures you control get +1/+1 for each bloom counter on From a Seed.

At the beginning of your end step, untap all lands you control. You may put three +1/+1 counters on target land you control. If you do, that land becomes a 0/0 Treefolk creature with haste that's still a land.

If you would lose unspent mana, that mana becomes colorless instead.
