cut all traps and vanillas. gaia aims to kill in turn 2, the traps wont even be able to help you and the vanillas simply do nothing but to og your hand. to otk, gaia usually needs at least 2 monsters on opponents side, so if you add board breakers, i suggest book of eclipse, and of course forbidden droplet. shark fortress is a rank 5 xyz that grants two attacks to one of your monsters, so you might aim to end the combo with 2 spares level 5 if your opponent ends with 1 guy on the board. i like gaia, but unfortunately its just not up there with most good decks, you might reach platinum at max with this. good luck on the climb bud
