Recommended Deck “Nanashi Mumei Deck”

Start off by placing Debut holomem on your stage, building up your holoPower through collabs, and using support cards like hSD01-016 Harusaki Nodoka or hBP01-113 Promise to organize your hand. Ideally, use hBP01-104 Normal PC is one of a good option, to place 1–2 of Nanashi Mumei, IRyS, and Ouro Kronii each on your stage.

Mid-game, bloom your Debut holomem into their 1st holomem. With the bloom effect of hBP01-019 Nanashi Mumei, holomem with #Promise can bloom into their 1st holomem. hBP01-030 IRyS wields an extremely powerful Arts on top of her bloom effect, making her a key piece to downing your opponent's holomem.
For flexibility, use the SP Oshi skill Amazing Drawing to add hSD01-016 Harusaki Nodoka to your hand when your options are limited, or hBP01-108 So, That Makes You My Enemy when you want to go on the offensive.

Towards the end of the game, bloom hBP01-020 Nanashi Mumei and hSD01-007 IRyS to down your opponent's holomem. Both holomem have Arts that get stronger the more holomem you have on your stage, so aim to keep six holomem on stage whenever possible.
If your holomem is about to be downed, protect them with the Oshi skill, Guardian of Civilization.
