Combos Utilizing Morphling

unblockable, pumpable, and cant be the target of anything for 1 blue mana....a nearly invincible demon of death...

you send all their stuff back to their hand

Tap Morphling or Horseshoe Crab with Kyren Negotiations dealing a damage then untap it and repeat till out of mana.

braingeyser and fireball in one!

tap morphling, hermit crab, or brass man to deal one to opponent and draw a card. pay u or 1 colorless mana to untap. repeat as necessary

just place the arcane teachings or something like psionic gifton the morphling to create a masticore-like effect. just ping a creature or your opponent, untap the morphling, then repeat.

the abyss cant kill statue and morphling cant be target of spells or abilities when yer opponent has no creatures, kill him

sac the 4 seals to give morphling +12/+12, then attack for 17 flying damage doubled(34 damage), then use relentless assault and attack again and win the game

oath for any of the three, then next turn oath again and then again and you have all 3 park the tokens from the feeder to the weaver and (if you have extras put them on the "morph-thing."

The Morphling untaps for one blue mana, and that means you can tap him multiple times to do damage, not only that but when charisma is on him you can gain control of all fo the creatures in play...
