This is a bit of a copout, but looking at this thread
viewtopic.php?f=57&t=1521 I see that my original challenge deck for Shandalar 2.0 already meets my ban conditions, and I am unable to find anything else that works so far. Hulk
Flash might make it eventually, but round 9 is really hard for it, and round 10 will be about as bad. Anything else I can think of that might work uses cards I have banned for myself.
edit: my original deck for BANNED! also meets the requirements, so I'll skip that one, too. Since part of the point of this thread is to find easy to play decks that don't use the same old cards, I don't have a problem just referring to that :p
-The deck for 5:1 (then 10:1) that I used also meets my banned list, though that is by no means an easy deck to play. However, there IS no other deck to play for that one, except with minor variations.
Looking at my challenge set #2 decks:
Super Mulligan - technically meets my banned list, but I used contract from below :p
What Hand? - Does not meet my banned list, I used Oath
That's Big... - meets my banned list
Epic - Does not meet my banned list, I used Bridge
There can be only one - has
Serum Powder,
Cursed Scroll, and
Goblin Charbelcher, but since this is a 100 card highlander deck, those can easily be replaced by almost anything else, and this challenge is easy anyway, nearly any deck will work
March of the Machines - meets my banned list
Land Ho! - I haven't beat this one at all. There's only one deck to try, too, and I didn't ban any lands
Dude... - meets my banned list, and this is basically the only deck to use anyway
So, Super Mulligan, What Hand? and Epic include banned cards. I'll try those ones with other decks. So did There Can Only Be One, but replace those 3 cards with anything and it should be doable easily; alternatively, any decent deck you can come up with should work, since the AI gets no advantages in this one.
edit: Ok I have decided... back to Land Ho :p I'm not going to finish this project unless anyone is really stuck on one particular challenge.
