In Jump Scare, there is cute synergy with the scry ability, which lets you check the card before resolving the trigger off Zimone
Advent of the Wurm: Much like Azorius Charm, it's a card that would clearly be Cube-worthy if the mana were consistent enough

It is worth noting that I have been playing with cards from the first two UK releases which I believe encompass the first three Japanese sets, but this format seems to be decently balanced which is always a plus in terms of having a good experience with the game (outside of Green but that's probably just because I have no idea what I'm supposed to be doing with the deck)
In these drawn-out matchups, having superior survivability and value is exactly where OP11-041-nami thrives
