While you need burden counters on The One Ring to actually draw a card, which technically is a restriction, tapping it puts a counter on it before you draw, so unless theres something like a Solemnity out, there is no restriction here
Whenever a modified creature you control attacks, double the number of each kind of counter on it
Then it has an attack trigger to make its power in 1/1 rabbit, so it's spawns a lot, and that's not counters but power so base one and then it can also include Auras like Rancor, equipment like Bonesplitter or Sword of Fire and Ice or +1/+1 effect from enchantments like Glorious Anthem
4-cost Borsalino is better for a defensive approach
To me it is just a fine filler card
If you don't control an Army, create a 0/0 black Orc Army creature token first.) Sorcery Gix's Command Choose two Put two +1/+1 counters on up to one creature
