Update on Agu-Bond Rush using ST20 Agumon since it can Warp if you have 3 or more Tamers with different colors out. BT21 Tai can get you extra draws to dig deeper into your deck as well as play ST20 Agumon for free to warp into Promo War and blow something up keeping a big blocker. Sequence on Deletions on BT14 SkullGreymon with BT17 Greymon to play Tai tamer out first so your Agumon can have Rush.
Tried to find room for BT21 WarGreymon, BT21 Greymon, and BT21 SkullGreymon as well as ST20 WarGreymon ace. However I firmly believe the above list contains all of the strongest choices for the deck while remaining as consistent as possible.
