Fiery Inscription Marcy: Again, this card is decent in the sense that it greatly benefits spellslinging Commanders, but the tempting mechanic is once again relevant to consider as a part of this card's value in your deck
Note that you cannot attack one player and exile a creature of a different player
In Commander, you have room to play the cards you like
If someones trying to blur that line, thats not a proxy conversation anymore
An effect like Impulse doesn't have the word draw in it, so it doesn't count for Sheoldred
Strong card flow, no one cares about life loss in Commander, and you can add loyalty counters to your other 'walkers without pulling planeswalkers and then you can add in +1/+1 counters to your stuff and counters onto Helix Pinnacle to win and then poison on foes and then also -1/-1 on their stuff
