So I think I'd like to keep it as a 2/1, however if it was created in a format that contained gut shot or something similar, I would up it to 2 toughness
Drawn To A Fight does help you play John Silver a little faster, reducing the cost down to just six if an opposing character was damaged this turn
If you want to stick to that style, they can be a little trickier to upgrade, but its worth it for the pure artistry and theming on offer
Discarding cards is barely a cost, especially with cards like Inti, Seneschal of the Sun and Containment Construct that turn it into card advantage
You dont really want to kill some random Kor Soldier token, but how many triggers of Umezawa's Jitte can you give your opponent
Outside of affinity, these are just great with cards that want you to have tons of artifacts, like Emry, Lurker of the Loch, Cyberdrive Awakener, or Urza's Saga
