Éomer, Marshal of Rohan
Kari Zev, Skyship Raider
Helm of the Host
Phyrexian Altar

   Prerequisites

What do I need to start this combo?
All permanents on the battlefield.
Helm of the Host attached to Éomer. Kari Zev does not have summoning sickness and cannot be blocked and killed by an opponent.

   Steps

How does this combo work?
1
At the beginning of your combat phase, Helm of the Host triggers, creating a nonlegendary token copy of Éomer with haste.
2
Declare Kari Zev as an attacker.
3
Kari Zev triggers, creating a legendary 2/1 Ragavan creature token that is tapped and attacking.
4
Holding priority, activate Phyrexian Altar by sacrificing Ragavan, adding 1.
5
When Ragavan dies, each Éomer that hasn't triggered this turn triggers, untapping all creatures you control and causing you to get at least one additional combat phase after this one.
6
Repeat each combat phase.

   Results

What do I get from this combo?
Infinite combat phases
Infinite creature tokens with haste
Infinite death triggers
Infinite ETB
Infinite LTB
