Notes & Combos
So there are some aspects to this list you might find confusing/new, I'll walk through them below.
**Why only 1 Abysspike? **
To do the main combo you only need the 1 abysspike, and I find it to be the worst normal summon in the deck. I would rather use the deck space towards something else as even when opening the pike it very rarely feels like a hard brick. You could run 2 here though.
Why the Icejade cards?
Not only can aegirine help to extend/push for OTKs by being sent off poseidra and then revived, it's a relatively free search off of abysspike in the combo which would otherwise just be grabbing discard fodder. Due to chaining you can safely use aegirine and minstrel's on field effect without losing the ability to put dragoons on top of the deck to draw with crocodragon. Being able to set up an additional synchro 10 or link 2 can feel very worthwhile and none of the cards are really hard bricks.
