GG WP! Indeed that was a fortunate draw to get rid of the Basilisk, though realistically I was likely to get it (was drawing 6/8 in that cycle). I was prepared to sac Oni to do nearly the same combat, just would’ve meant killing Mimic with the Nullcraft and maxbanding River instead of River dead and Mimic alive.
I was definitely trying to carefully play around Polymorph: Squirrel, was a delicate dance and was a little surprised not to see it but also I intentionally made sure not to leave many/any openings to utilize it for a kill
