Your cards are worth of what they usually are, as for every card you draw in your draw step, your opponents draw a collective three
In a Commander precon that will likely get to turn seven+, it's well worth it
If you put a counter on a permanent that has no mechanical relevance, it just sits there waiting to one day be useful
You can choose to loot a card, grow the equipped creature with a +1/+1 counter, or untap two lands (which basically pays for the equip cost)
Shared Animosity is another useful cards as it rewards us for going wide with Sethron, Hurloon General and making our attacks hurt even more than before
That deck may suddenly get much worse, but I'm sure it can adapt with the right artifact destruction spell
