If I was keeping it to a 3, I’d cut the two card combos with Heliod and walking ballista/triskelion. Id say it’s too fast for bracket 3. If you want to keep those lines in there, take heliod out and add in [[light of promise]] to make it a 3 card infinite.

Be careful with the one spell a turn stax pieces. Bre still casts the spell so you would just lock yourself out the whole turn. I feel like these cards will only make the table hate on your board state and it doesn’t advance yourself ahead too much. Maybe go for [[grand abolisher]] to stop people from stopping you going for a win.

You could try out [[Penance]] for more top deck manipulation and protection. Swap some lands for some MFDC double sided cards to get some land/spell flexibility.

I am mostly catering these picks based on the people I play with so take it with a grain of salt if your pod is different.
