MTG Combo: Brago, King Eternal + Strionic Resonator + Thran Dynamo

If you deal combat damage to a player with Brago King Eternal while you have Strionic Resonator and Thran Dynamo out, you can copy the effect by activating Strionic Resonator's activated ability by tapping Thran Dynamo for three mana and have the copy of the ability target Strionic Resonator, Thran Dynamo, and any number of other legal permanents. When that ability resolves, you will have an untapped Strionic Resonator and an untapped Thran Dynamo to repeat the process infinitely for infinite mana and infinite enter/leave the battlefield triggers.
