I didn't think about that. Solphim is double the damage and possibly indestructible.You would be a number 1 target from the jump. If you want to be less threatening I'd prefer Torbran as the commander because you are playing red and if he gets removed you would like to be able to recast your commander and continuously deal the extra 2 damage with the Dragon's Approach. If Torbran is in your 99, you need a way to put him on the battlefield consistently or get him from your deck. It's possible with chaos warp and a deck filled with the other card types not creatures to make this happen.
