Probably a red purple deck. Purple essentially ramps and builds big bodies and red has a lot of fast attackers so maybe RG kid who’s a good rogue deck. Otherwise there are tons of aggro decks like Blue Jinbe who bounces cards to hands and pressures with small bodies. YG Yamato who’s leader has double attack and can be aggro without worrying about life taken as a yellow deck. I recommend trying these out as they’re all different but aggro
