Fusion in both instances, but honestly I deeply adore every summon method except for Link.... Synchro, Fusion, Ritual and XyZ cards are all like painfully pretty - the specific shade of Ritual blue is for me maybe the most perfect blue anywhere short of Klein, but Link... i'm sorry, but the frame/design of Link cards is deeply ugly to me. I hate the mock cyber hexagon greeble, I hate the enormous arrows and I hate that they omit the level stars, objectively the prettiest possible "at a glance "card power eval metric.
