Ryu-Ge Dino

This deck is incredibly flexible both in its endboard and in its decklist. You can put in handtraps, sub out Kaitoptera for Giant Rex if Polymerization is too much of a brick, and throw in a lot of different extra deck options.

Mistva pops itself for cost which sets up for Xeno Meteorus, and War Zone can search for any Dino you need. Those are your main segues from Ryu-Ge into Dino, but the deck does suffer from not going the other way around, so if you can't get Mistva or War Zone, then Sea Spires and Wyrm Winds become bricks without the respective monsters and you're stuck with Dino combos, which are nerfed due to limited options
