Notes & Combos
Trishula is your out for Avramax. I've not made Tzolkin yet but it's possible. Plenty of equips in deck to throw into the bin to fuel Isolde.
Sublimation Knight is probably the best starter, use its effect to attach Squeaknight, then SS it to the field for an easy Isolde, but DON'T use Squeaknight's effect on summon! It'll only allow you to summon once more from the ED if you do!
Neo Space Connector and Neo Spacian Aqua Dolphin are also potential includes if you don't have/like Sublimation Knight, and also lead to an easy Isolde.
