Zethi, Arcane Blademaster | Lithoform Engine | Dramatic Reversal

Cards

Dramatic Reversal is exiled with a kick counter on it.
Zethi does not have summoning sickness.
Nonland permanents you control can tap to produce at least ({4} magic symbol) ({U} magic symbol) .

Declare
Zethi as an attacker, triggering its second ability.
Holding priority, activate all mana producing nonland permanents you control by tapping them, adding at least ({4} magic symbol) ({U} magic symbol) .
Activate
Lithoform Engine's first ability by paying ({2} magic symbol) and tapping it, copying
Zethi's triggered ability.
Resolve the copy of
Zethi's ability, creating a copy of each card exiled with a kick counter of it and causing you to pay ({1} magic symbol) ({U} magic symbol) to cast the copy of
Dramatic Reversal.
Resolve the
Dramatic Reversal copy, untapping all nonland permanents you control.
Repeat from step 2.
Once you have infinite mana, you may use that mana to then cast the copies of all other cards exiled with kick counters on them.
