When Rograkh dies, Mortuary and Remembrance trigger.
Resolve the Mortuary trigger, putting Rograkh from your graveyard on top of your library.
Resolve the Remembrance trigger, searching your library for Rograkh and putting it into your hand.
Resolve the Woe Strider ability, causing you to scry 1.
Cast Rograkh by paying 0.
Repeat.
This delightfully twisted loop uses Woe Strider as the sacrificial altar for Rograkh, Son of Rohgahh, whose zero-mana cost makes repeating the process effortless. Whenever Rograkh meets its end, Mortuary immediately intercepts the creature card and places it right back on top of your library, perfectly positioned for Remembrance to fetch another copy straight to your hand. Because you are constantly cycling the exact same tiny hero, Woe Strider’s sacrifice ability fuels endless death triggers, scry filtering, and storm count without ever running out of fuel.
