It can't get past a Blade Splicer...Tusk is great against burn, it is nice to abuse with flicker effects and Recurring Nightmare but outside of that it is not so impressive
I imagine it has a home in 99 of GBx decks rather than the command zone
Pushing your deck above 60 (or 40) cards makes it harder to find key cards, increases the risk of "mana flood" (drawing only lands, so you have nothing to cast) and "mana screw" (drawing too few lands, so you can't cast any of the spells in your hand), and makes it more likely that you'll draw unplayable hands
These unblockable creatures provide you with further avenues for theft via Gonti, Canny Acuisitor , Dream-Thief's Bandanna , or Arcane Heist
If the player plays alone at a priority table, their opponent from the non-priority table will win by default and earn 2 points
It's a 3/3 or 4/3 in the midgame and could be better by the late game
