Enchant two nonland permanents you control
Once each turn, when you activate an ability of one of the enchanted permanents, you may put a +1/+1 counter, a loyalty counter, or a charge counter on each enchanted permanent. (They can be different counters.)

Coalesce {5}{G}{G} (You may cast this from your graveyard for {5}{G}{G}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

control.

When Beyond the Veil enters, if it was cast, another target nonland permanent phases out. (Treat it and anything attached to it as though they don't exist.)
Nonland permanents you don't control with mana value 3 or less can't phase in.

When Bezoarbeast dies, each opponent loses 2 life and you create a Vial token. (It's an artifact with “{1}, Sacrifice this and another permanent: Draw a card. Activate only during your turn.”)

Target creature you control becomes a copy of another target creature you control until end of turn.
Showcase {2}{U}{U} (Then if you cast this for its showcase cost, create a 1/1 red Bard creature token that can't block and exile this. Whenever it attacks, you may cast a free copy of this.)

Create two tapped colorless land tokens named Far-Off Lands with “{T}: Add one mana of any color.” (Then exile this card. You may cast the creature later from exile.)

Look at the top ten cards of your library. Put any number of legendary permanents with total mana value 6 or less from among them onto the battlefield. Put the rest on the bottom of your library in a random order.
For each planeswalker you control, you may activate one of their loyalty abilities. (You still pay its costs.)
