VamdeEX

A purple deck based on using Myotismon or Vamdemon.
Malomyotismon is usually played with the effect of BT3's arukenimon and mummymon, however since I want to inheritables to stay, I will not be playing those 2.
This in turn will make Malomyotis a very very heavy cost of 5 evo.
The Level 5s played in this deck are both Myotismons. One of which is 2 cost to evo, the other reduces the cost of a myotismon by 1.
Its still a cost of 7 in total either way however, if pulled off according to the game plan.......

With both Devimon or xiaomon later in the game and Myotismon Inheritables, Malomyotismon becomes capable of attacking Active Lv4 and below digimon and he has piercing and the ability to gain 1 memory when a digimon is deleted.
Considering this deck's style of ramming Retaliation digimon into the opposing digimon or player, self-destruction is almost always going to happen so gaining memory off them is good too.
It is probably better to go into Vemomyotismon first before Malomyotismon though, chronological order am i right? Hahaha.
Best lines of evolution would be, 
Gabumon - Wizardmon - Myotismon - Vemonmyotismon
Tsukaimon - Devimon - Myotismon - Malomyotismon
Still need testing, but the deck runs slow, most probably a causal deck at best.
