Girls rule boys drool etc etc Im running a 25-card list to slot in some more backrow removal, Eclipses, Necro Fusion to occasionally cheese opponents with Quintet Magician, and 3 Car Turbo to make the motorcycle going 1st and potentially extend through disruption going 2nd (also the attack boost in GY did come up!), personally I found a 20-card list resulted in too many hands where I only opened engine cards
For instance, the Final Fantasy crossover includes double-faced cards to represent iconic characters, minigames, and story moments
However, it will probably remain at least a $10-15 card now
Whatever format you choose, the main idea is to pick the cards that have those special anime variants
Mould Shambler is nice as it hits walkers but less useful with pod and recurring nightmare
Saffira, Dragon Queen of the Voiceless Voice effect, discard itself as cost, send Prayers of the Voiceless Voice from deck to graveyard, then add Sauravis, the Ancient and Ascended from deck to hand
