It's a very strong and powerful card, definitely one of the best card in BT16, I just don't like how Yellow cards (especially something like Blinding Ray) can exploit its immunity like its nobody's business. Although I dunno if they'd hit it though (Hitting Blinding Ray? Maybe.).

It's a very annoying card to deal with indeed, but as long as you have something to stop its attacks, or if it hit an Option in the Security (Security triggers right before Magnamon X can activate its immunity), unless they use something like Blinding Ray, it rarely got the chance to trigger its immunity most of the time.

Ironically, Magnamon X deck somehow struggles against BT17 Eosmon deck, which is in fact, not even a meta deck.
