So i've gotten my hands on an Iona deck with lv5 Mayu and Iona. Right now im quite confused whether to use Poison Fangs or Ancient Weapons. I currently have 2 Violence Splashes so I want to use it so I want to know if it Rikabuto or Marsface combos better with it. It would be extremely useful for me to know which signi type works better with which lv 5 lrig as mayu and ultima functions quite differently. With Necronomico, it kinda forces me to grow to Mayu to use its skill so I don't know if its worth it or not. I feel the deck is very vulnerable at lv1 and lv2 because texahammer basically does nothing early game due to not having any millers (eg. Kythera). Lv2 signis Azteca and Megatron also feels very mediocre as both somehow leaves a hole on your field and there powers are abyssmal. With the whole deck taking up all the lifebursts, i dont even have space for servant D's 5000 base power. With the Triumph's search targets being mediocre, it is quite hard to play against decks like Midoriko or even Umuru as the early game is quite weak. With lv3 and 4 having tons of magnificent signis like kythera, pyramid, it leaves no space for lv3 guards which makes the deck have 8 guards which im not sure if it is enough when playing lv5 iona. For ARTs if im playing Necronomico, im not sure whether to play Dark Matter or no, right now it has 1 Baroque Defense and 1 Ancient Surprise, deciding what to use for the last one. Im thinking of either Bloody Slash, Dark Matter or Idol Defense.
