Cleansing Nova is a moderately-costed board wipe that can either function as a slightly more expensive Wrath of God or hit all artifacts and enchantments instead, which should make for a more one-sided wipe against decks that focus on artifacts/enchantments
After opening the ETBs for this set and getting a look at the full card list, I was beyond excited for several Full Art options that can be found in booster packs for the expansions
Shadow Rider Calyrex Vmax ( $40-75) We start off our list with the Shadow Rider Calyrex Vmax rainbow rare
Islandhome gives the creature islandwalk, but it also makes you sacrifice it if you control no Islands

In general, Leader Nami has two strong effects, so she was mainly just missing the right support cards to push her to the next level.
