Rhapsody {5}{U}{U} (Pay {5}{U}{U} to cast this as a 4/4, or once it is in play to make it become a 4/4.)
Animus Channeler's rhapsody cost can be paid any time you could cast an instant.

At the beginning of combat on your turn, target creature you control has base power and toughness 5/5 until end of turn.

Gain control of target creature until end of turn. Untap that creature. It gets +1/-1 and gains haste until end of turn.

Double each number and amount of target instant or sorcery spell, activated ability, or triggered ability. Its controller may choose new targets for it. (Amounts are number words, X values, and “a” or “an” used as 1.)

Whenever you cast a noncreature spell, if you control exactly one creature, copy that spell. You may choose new targets for the copies. (If it's a permanent, it resolves as a token.)

Tap an untapped creature you control: Put a charge counter on Channel the Spirits.
Remove nine charge counters from Channel the Spirits and sacrifice it: Creatures you control get +3/+3 and gain trample until end of turn. Activate only as a sorcery.

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.

{T}: Add {C}.
{T}: Add one mana of any color that a basic land you control could produce.

When Chantwood Channeler enters the battlefield from your graveyard, it gains haste and creatures you control get +3/+3 and gain trample until end of turn.
{5}{G}{G}{G}, Sacrifice a creature: Return Chantwood Channeler from your graveyard to the battlefield. Activate only as a sorcery.

{T}: Add {G}.

{T}: Add {G}.

Whenever Fallacy's Channeler becomes untapped, each player sacrifices a creature.
{T}, Pay 1 life: Fallacy's Channeler deals 1 damage to any target.

When Fireheart Channeler dies, you may exile it. If you do, put a blaze counter on target land without a blaze counter on it. As long as that land has a blaze counter on it, it has “At the beginning of your upkeep, this land deals 1 damage to you.” (The land continues to burn after Fireheart Channeler has left the battlefield.)

{U}{R}, {T}: Fulmen deals 1 damage to target creature. When a creature dealt damage this way dies this turn, draw a card.
Whenever you cast an instant or sorcery spell, if you cast another instant or sorcery spell this turn, exile Fulmen, then return him to the battlefield transformed under his owner's control. He deals 3 damage to each creature.

When Glowskate Channeler enters the battlefield, create a green Aura enchantment token named Manta's Wings attached to target creature. The token has enchant creature and “Enchanted creature gets +2/+2.”

Enchant land
Enchanted land has “{T}: Draw a card, then discard a card.”

{T}: Add {C}.
Whenever you tap Primal Channeler for mana, the next creature spell you cast this turn can be cast as though it had flash.

Whenever Whitepeak Channeler deals combat damage to a creature, tap that creature. That creature doesn't untap during its controller's next untap step.
