Scuttling Sliver + Trazyn the Infinite + Oko, Lorwyn Liege // Oko, Shadowmoor Scion + Arc Reactor

Scuttling Sliver

Trazyn the Infinite

Oko, Lorwyn Liege // Oko, Shadowmoor Scion

Arc Reactor

How it works

1. Activate Oko's first loyalty ability by putting two loyalty counters on it, causing Trazyn to gain all creature types until end of turn.
2. Activate Trazyn using Arc Reactor's ability by tapping it, adding CCC
3. Activate Trazyn by paying 2, untapping it.
4. Repeat from step 2

This ingenious setup transforms Trazyn the Infinite into a one-man mana engine by leveraging the passive graveyard-absorption granted by Prismatic Gallery. Because Arc Reactor rests peacefully in your graveyard alongside other necessary pieces, Trazyn borrows its tap ability to generate three colorless mana at a time. To keep the loop going, Scuttling Sliver's static ability grants its untap power directly to Trazyn, allowing the {2} untap cost to be easily paid out of the generated surplus. Meanwhile, Oko, Lorwyn Liege // Oko, Shadowmoor Scion aids the synergy by temporarily altering types via its loyalty framework, ensuring all the moving parts align seamlessly to flood your mana pool.
