First take on a CresGaruru deck.
I want it to play out like a typical midrange deck. Scale up the ladder with mostly Garu line and some protection. CresGaru can OTK, but it is not necessary.
Nokia - Reduces cost of 16 mons.
Matt, Vilemon - Start at 3 memory and give yourself some time to climb up to mega
WereGaru -Use inheritable first to activate BlackGrowl, gain memory off Guilmon
Garurumon, MetalGaru - Just to show options of alternatives, change numbers as you like
SkullGrey - Reduced by Nokia, adds an extra source for digiburst, can also make your rookies/blockers threats late game.
