meh to beckoning. it's not bad but i'd rather run avarice which, iirc, i already do. both cards let me recycle powerful cards but avarice is a gamebreaking topdeck that's live very fast in this deck (since, although you obviously wouldn't want to, you could recycle normal monsters to reach 5 if you had to) where as beckoning is a horrific topdeck, and you burn hand advantage really fast in this deck to make the big plays so the likelihood of getting a big recycle off beckoning is slim compared to avarice.
@bluestar: your approval of my build means a lot to me =P econs strike me as the best way to get around the troublesome raiohs and roaches. econ a geb to steal the offending monster, pull a seal from the deck and tribute the seal to ss another from hand (preferably nephthys since you can use nepthys to kill roach, and if you tribute another holy mark it'll be a +0. if you're dealing with raioh, you can ss an alexandrite instead and exceed off with the raioh to infuriate your opponent). there's also honest, ofc.
