Hello! This is a easy deck to play but I will give some tips to play it.
This is an evolving deck, so you need to play it slowly but using some cards like rookes or champions to attack and have advantage. there is some cards with the effect of "recovery deck", so reserve it and use it when is needed. when you digi-evolve your first mastemon, I recomend to no attack with it, just in the las security card, so you can have it till the end.
if you like an explanation of the deck, or you have a recommendation, just comment :)
