Crouch start with a left hand sidepull in the overhang and a right hand on the lowest part of the arete. Slap up the arete to a dynamic move into the crack. Top out through the crack as per The Alexisizer. Starting higher with the right hand eases the difficulty. Originally done from a sit start prior to the ground eroding.
The first two bump moves were the crux for me. The jump I practiced from the ground into the underhand catch as suggested by @yoimron. Fun stuff. Easy topouts. 👍
