You can be a multiversal threat like Nicol Bolas the Dragon-God, the most ancient evil in Dominaria
He unites the red-white Equipment synergies with red-green big creatures under the seven power theme
Many of these creatures have powerful secondary abilities including creating additional creature tokens (Bladewing, Death Tyrant, Feldon, Kari Zev, Krenko, Mardu Strike leader), drain/life loss (Calculating Lich, Hellrider), direct damage (Combustible Gearhulk, Dreadhorde Butcher), anthem/buff effects for your army (Drana), card draw/free spells (Etali, Florian, Garna), additional combat step (Moraug), and many more
I think both decks will be fun to play and have the potential to be upgraded into more powerful versions
While I live far away, im definitely going back
Blue has plenty of cards like Aphetto Alchemist and Fatestitcher to untap this and draw multiple cards, and you can repurpose many of those cards into combo pieces that win the game
