The Porg Patrol would like to issue the following formal challenge:
'Common Man' 3v3 Rare characters only. No legendary, uncommon or starter cards permitted in your deck. Limit of 10 rares max in your 30 card draw.
(Yes that was a copypasta)
Interesting challenge I thought I'd do it too.
Not sure if uncommon battlefield is allowed please tell me if you are the one running the challenge.
