At the start of combat on your turn, you get to put +1/+1 counters on another creature you control equal to their power
One of the added abilities was artifact creature focused (granting +1/+1), but the other two were just generally useful abilities that would help you smooth your draw and cast extra cards
With more generals and card choices come increasing decision paralysis and its for this reason that I recommend preconstructed Commander decks to most players
I would switch this card out for something better, and maybe something that didn't cost five mana
The same is true for first strike, double strike, deathtouch, haste, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance
