I have notice one thing while playing this deck. A statement from someone who plays against this deck for the first time. They'll ask to see my commander and I show them and they'll always say "Oh a life gain deck". I say "Yeah and no, you'll see". Once you play for example
Pain's Reward and start the bidding at 38 or 39 life, tap the commander to put 38 or 39 counters on a
lifelink creature then they take a second look at the commander and go "Oh it also goes for life you lost". That part most people skim over reading until they see it happen on the battlefield.
