Under $25 Morphs that Win (Casual)

Ensure you have 3/4 lands when you start, missing land drops hurts a lot. Best Turn 1 is often forest +obscuring aether followed by a turn two morph. Do not be afraid to block early game because you want to make it to the late game where you can easily out-value your opponents.

Use morphs as utility, add and remove them based on what decks you're up against. Deathmist Raptors for discard decks, Ice Feather Aven for Token Buff decks, Ainok Survivalist for heavy enchantment and artifact decks. Must keep morphs are Willbender, Vesuvan Shapeshifter, Deathmist Raptor and Den Protector.

Vesuvan Shapeshifter + Brine Elemental = Pickles Lock, soft lock
Vesuvan Shapeshifter + Secret Plans = Card Draw
Face Down Creatures + Trail of Mystery = Makes sure you donèt miss a land drop and thins out your deck

Prophet of Kruphix - Pays for itself, more flexibility with morph. If it dies, you can copy it with Vesuvan Shapeshifter or bring it back with Den Protector
Deathmist Raptor - Great value with even 1 in your graveyard
Vesuvan Shapeshifter - Always 4, great flexibility in using already face up morphs, can draw an extra card a turn with secret plans
Ixidron - board clear and catch up mechanic. You really mess up creature based decks
