Icejade Combo

Icejades love level 10s. They have an easy time getting to WATER Synchros, have a level 10 that plays itself, and can utilize Finis Terrae effortlessly. This deck, then, wants to use these level 10s to form a large board of heavy hitters to swing for game with the protection of Gymir Aegirine to keep opponents at bay.

Card choices:

True King Bahrastos, the Fathomer - We struggle with backrow, simple as. This not only covers us in that regard, but also lets us use Boss Stage, one of the better fields out there, i na deck that needs a field, and gives us more food for Nidhogg, Generaidfer Boss of Ice.

Gameciel, the Sea Turtle Kaiju - Easiest Kaiju to trample over, and WATER attribute means it works with our effects. This deck could easily afford to run more Kaiju stuff if you prefer that over Generaider setup, but it runs the risk of not having WATER attribute in hand and field.

Nidhogg, Generaider Boss of Ice - Negate, WATER attribute, free summons with Generaider Boss Stage. Feels like a shoe-in.

Guardian Slime - We have to Normal Summon lots of Monsters with weak ATK stats. This rewards us for that and lets us build up that level 10 board easier, bonus WATER attribute.

Number XX: Utopic Dark Infinity - We need power, so this is there to give it to us easily. Also lets us take powerful Monster cards fro mour opponents or even protect our own effects on the field. A board breaker that also builds up our own isthe kind of give and take we need in this deck.
