Notes & Combos
Aqua Dolphin is the best card in the deck.
So, I grinded again with the Isolde version of Heroes. I strongly believe that this version is better than the pure version of Omni Heroes. There where many games that I played throught 2-3 handtraps and still ended on great boards because of the lack of Hero locks. There is not a big choke point because you can pivot your combos. If your Stratos or Vyon or Blazeman gets interrupted, then you can go for Isolde and combo. If Isolde gets interrupted then you can go for S:P Little Knight and Verte into DPE.
The combo is very fluid and it depends on what your starting hand is, however a usual path of the combo is 2 warriors -> Isolde -> search Neos -> Special Vyon -> send Shadow Mist -> search Liquid -> get Poly -> Flame Wingman -> Cross Sheep -> Sunrise -> revive Vyon for 2nd Poly or Stratos for search and then depending on what you started with, you can end on DPE, Apollousa (or Verte, S:P), set Favorite contact for Neos Wingman and you can get hand knowledge and handrip with Aqua Dolphin or Shadow Mist into Mask Change by popping Wake Up with DPE and summoning a warrior from the deck.
Going second the deck is still strong, however you have to open very good because most boards are really hard to break. Hero Lives, Droplet and Thrust are your friends. It hurts to lose Trinity from the Extra Deck, however all cards are useful and Trinity is very situational. Cross Crusader is not used in the main combo, however he is vital late game and if your only starter is Fusion Destiny, you can use him to end on DPE + Plasma that is still a pretty strong board. Also Phoenix Gearblade is amazing for OTKing with very few Special Summons. Even if your Isolde is negated you can use her effect for the cost and get back the Blade for OTKing or discard fodder. It is literally a free card.
