Enchant creature
Enchanted creature gets +1/+1 for each artifact and/or enchantment you control.

Exile target nonland permanent. For each of its colors, its controller creates a 1/1 colorless Spirit creature token.

Draw four cards, then untap up to two target lands.

When Channeler of the Veil enters the battlefield, create a 1/1 colorless Construct artifact creature token.
Sacrifice another creature: Each opponent loses 1 life.

Entropic Inferno deals 5 damage divided as you choose among any number of targets. At the beginning of the next end step, for each permanent dealt damage this way, its owner puts it on the bottom of their library, then reveals cards from the top until they reveal a nonland permanent card. They put that card onto the battlefield, then shuffle.

Exile up to two target creatures controlled by different players. Return those creatures to the battlefield under their owners' control at the beginning of the next end step.

End the turn. If it's an opponent's turn, they take an extra turn after this one. (Exile all spells and abilities from the stack, including this card. The player whose turn it is discards down to their maximum hand size. Damage wears off, and “this turn” and “until end of turn” effects end.)

Counter target instant or sorcery spell. If that spell is countered this way, exile it instead of putting it into its owner's graveyard. You may cast that spell for as long as it remains exiled and you may spend blue and black mana as though it were mana of any color to cast it.

Nonstoried creatures lose all abilities and have base power and toughness 1/1.
