Considering to build black version so it can search anything and not bottoms tamers.
Still powerfull, I dislike BT12 greymon bc it clashes with bt14 agumon, if you have no further plays, either you drop a bt12 agumon or a bt12 tai to trigger bt14 agumon in breeding next turn and speed up the deck.
WG may be the better option, however, I prefer the solid control BWG and BWGX gives you, being able to clean the whole field if you calculate everything right.
My favourite Digimon, and my favourite deck, without a doubt.
Small change: another BT8 metal, sometimes you just need to de digivolve some things before you attack at all.
