And that’s that! I will no longer be working on new cards for this archetype (At least for a while) but I will correct any mistakes I made text wise. As always, feedback is always appreciated and I’ll see y’all later!

[Loleo]

Glad to see the changes and I can't find any glaring issues you didn't already address! Can't wait to see what others have to say!

[Ahmad Alzubi]

I wanted to point out this:
for "Acidic Slime", Link monsters with (Top-right and Top-Left) link Arrows MUST have this effect in their text:
"You cannot Special summon monsters to the Zones this card points to."
This is a Konami rule to avoid 3-monsters Extra-Link.

in regard of the archtype, reading in progress :D
