Other options:
- Kaiju's & Kaiju slumber: safe bet with some synergy. Side deck this package no matter what.
- new "trap track" card with a few impactful trap cards (D barrier, DD ground, IDP, etc..)
- Tour guide (consistency)
- More handtraps (nib doesn't hurt this strategy too much as you don't commit to the board too much on your opponents turn)
- Go second - DRNM, lightning storm, evenly, etc. - all work well since you don't have too commit too many cards to the field at any given type except when going for the kill
- Dark Spirits: I love them, but they're outclassed. If you play them you have my respect.
