There is two ways to win with this deck.
Option 1: deck out
Defensive deck which utilizes Necroface to deck out the opponent by removing cards from play.
Swap necroface between dimensions to win!
Since the deck itself is quite fast, ideally you activate "return from the different dimension" to summon and remove multiple necrofaces in your turn to deck out your opponent. Pass the turn to win.
Option 2: wait like a crocodile and strike at the right moment.
Giant trunade is meant to recycle cards which switch Necroface between dimensions.
However later in the game, you could normal summon a necroface, activate return from the different dimension, giant trunade and OTK your opponent.
