Masked HERO Anki is by far the best Masked HERO we currently possess based on his effect, stats and attribute. By sending a HERO monster you control to the graveyard, Mask Change allows you to special summon a Masked HERO monster with the same attribute from your extra deck. When Anki destroys a monster, he can search for any "Change" Quick-Play spell. Since Mask Change does not limit itself to once per turn, you can easily clear your opponent's entire field of monsters in one turn.
We currently do not have enough statistics on this deck to generate a breakdown. See below for recent decklists.
1st Place - Anytime Tournament - April 21, 2019 - Vanitur
Activating Forbidden Chalice in the Damage Step of Masked HERO Anki's direct attack resets his attack to 3200.
Remember that level 6 and above monsters cannot target Destiny HERO - Decider for an attack. Simply summoning him can sometimes give you the time you need to draw into a Mask Change.
If you are using the fusion option build, do not feel obligated to say yes to Destiny HERO - Dreamer's effect prompt the first time it appears. You may need it later to save a monster.
