Idea from
this.
I was thinking: theoretically, it's possible to make a deck that with full set-up can't be countered by anything*:
1)It must have Eternity and a low cost card to prevent deck-out
2)It must have something against denials/PC
3)It must have passive healing(Bonds: ok. SoG: ok. Miracles: not ok)
4)It must have a way to kill Enemy in case of another Eternity based deck with passive healing (something like a momentumed and quinted golem)
Obviously, rushes (and the other 99% percent of decks that are faster than this unbreakable turtle) kill him, so this isn't a deck that can win every match.
So, if you want, post here your (Half-)Unbeatable decks™!
There aren't rules, but follow this generic characteristic:
1)You need to get the (Half-)Unbeatable combo™ ASAP
2)A (Half-)Unbeatable deck™ with 500 HP is more difficult to kill than a 100 HP.
3)If you manage to deny your opponent before you set-up your combo, probably he won't ever have a chance to OTK you.
Have fun!
