When I play I'm allowed to use upped cards, I'm also allowed to use cards from my account even if they aren't in the original players deck. Just say 9270984 is in a matchup, I could drop in with a nymph based deck totally unexpectedly and trash dem whn they be thinking standard darkdevourer.
The only relevant section of the rules I can find is:
"1. Temporarily replace that team member with any other team member, including the General.
Temporary replacement player will use the same deck and mark that the original player would have used. Replacements (Generals and Lieutenants included) can never use any upgraded cards. They always use unupped versions of those upgraded cards. Penalty for using a replacement is that you cannot salvage any cards if you win!"
Note: this is where substitute is most effective because we'd still get to salvage 3 cards.
I don't see anything about you being able to use cards from your account (change decks) and that would be totally different from the last war so please show me where that rule is if it's changed.
Congratulations on the Nymphs guys, that's awesome!
Which nymphs might fit with our current plethora of decks? Purple Nymph is really strong and would be nice in the Lycan decks. Earth Nymph possibly in one of our earth decks, I dunno.
