EDHREC spotlights RogIshai, a tempo-control cEDH partner deck

The keep-and-mulligan decisions are pretty simple if you have played enough competitive Commander to know what matters. You want Rograkh, Son of Rohgahh online early because the deck starts with a zero-cost commander, and that changes how the first few turns play out. Rograkh is a 0/1 Kobold Warrior with first strike, menace, trample, and partner, so he gives you an immediate body in the command zone without spending mana. Commander rules still matter, though: both commanders begin in the command zone, can be cast from there, and pick up commander tax after each prior cast from there. Ishai, Ojutai Dragonspeaker, a 1/1 Bird Monk with flying, gets bigger whenever an opponent casts a spell, so even a hand that looks light on action can become a real threat if the table starts developing normally.

The primary win line is the clean one competitive players already know well. RogIshai slows the table with cheap interaction and efficient card flow, then pivots into Underworld Breach once opponents have been checked long enough. Underworld Breach gives each nonland card in your graveyard escape, with escape cost equal to the card’s mana cost plus exiling three other cards from your graveyard, and it sacrifices itself at the beginning of the end step. That makes the finish deterministic once the graveyard is stocked and the table is short on resources. The deck’s strength is not in goldfishing a flashy turn-two kill. It is in surviving with mana open, forcing bad sequences from the other three players, and then turning the graveyard into a win condition.
