Unfun fact: If you activate Calamity's trigger and you have more than one possible attack target (a planeswalker or battle) that ability glitches and creates only one token instead of two. Hopefully it gets fixed soon.
Wife is at work, baby is at Grandma's, I'm sitting on the balcony of my new apartment smoking a lovely cigar watching a fun magic deck. Life is good 😎 👍
On the second mono red match, i don't know if it would change much, but instead of playing Sokenzan to cast Calamity, you could've channeled it to have 2 blockers, so you would be capable of block the menace and the disguised creature.
