So I really love strategist helm and I have noticed it has some certain potentially negative benefits when an opponent casts certain cards.
So the first one I want to highlight is magebane. So potentially a mage can only take 2 damage per round when you cast both spells. But since the helm allows you to cast a command for free allowing it to potentially hit 3 times in one round.
The next card that this may benefits is Wizard opponents who use gate of voltari. in This situation gate can only gain up to two mana when a spell is casted and resolved. So with the helm the gate now can gain 3.
Now I still love this card I just want to let others know it may not always be optimal against certain strats.
