I've been thinking all day about the dumb combos i could do with traptrix and ryzeal, and then i get home and realize that i forgot about ext's restriction (i can't link into sera to search), ice not triggering on special summon, and sword needing a ryzeal body on field or GY to summon itself.

I can still make it work, i just need to run the field spell at 3 and accept the fact that my beloved sera won't be part of the endboard.
