MetalMagurumon X-Antibody or melga for short is a deck introduced in bt9, as most of bt9 decks, its a OTK Style deck, in this list, you can see the extra decks for cards that are played normally but i decided not to put, only modokimon isnt included but its used
The deck have 2 mains combos to win, you always want to make or prepare it in rasing area, first one is without x-antibody option card, if you dont have omnimon, you want to use a rokie or a different digimon to leave at the oponent at 4, this combo you must have promo weregarurumon(prefable in raising),3 memory, and gabu and garurumon(prefable with the x forms as well, cuase it will more likely die in one of the checks), with weregaruru you attack twice restanding(once if you danger losing it and domt have garuru x to savr him) then evolvr him into weregaruru x to restand and if you have 8 or more you will have the +1 check, then making the hit with to clean the last security, then evolve to metalgarurumon ex01, if you do it correctly, it will cost 2 cause its on play effect, then evolve it to metalgarurumon x to finish, or omnimon.
Second combo you gonna need to have 3 memory and weregarurumon promo ready as last combo, but different to last case, this combo can do 5-7 security checks and end game, in this case you will give him x antibody to him, you start attacking to security normally, then for his second hit, evolve it to weregarurumon x antibody, making the check +1, making 3 checks already, weregaruru x will restand and make another check, making this the 4th and 5th check, then like last time, evolve into metalgarurumon ex01, costing 2 if you did it correctly, then evolving into metalgaruru x to finish the game or at least making 2 checks more if they had more than 5 security, in this game you will need omnimon bt5 to finish game.
For this deck, i prefer running davis and blue memory instead of cards like hiro, A delicated plan, emrgency program shutdown or coctyus breath, cause this deck have a combo strong enough to win without to much trouble, the worst enemy is bad luck in security check, thats why some people play a delicated plan, but i prefer to max in search, so i can garuanteed or increase my chance to not have bad luck in hand and increase chance to have my pieces in hand, and hammer spark may help in security or do/play something that you oponent thinks you can, like if you had 2 memory, it would let you end game cause it will end with metalgarurumon evolving with the normal combo, but with hammer spark it will allow it and suprise the enemy.
And for last, metalgarurumon it a great deck to build for 2 reasons, first it isnt as expensive or hard to get as another deck in meta, decks as gaiomon or wargreymon x needs expensive and rare cards like bt1 tai and greymon, and the second reason its a deck that will mantain meta, or at least it will if it doesnt get any card banned.
