Its designed for Fusion Strike first, as its attack does more damage with that special energy card, but colorless energy requirements mean it might see some play in peculiar scenarios and its a real boon in limited play
Although it will be unable to attack during the turn in which it's played, you can use your Leader's effect to swap its power with a Character played on a previous turn, allowing that Character to attack in its stead
If the card states 'until the end of the Digimon's lifespan', the card remains in the slot even if your Digimon evolves or is sent to the Dark Area not via reaching its lifespan
There also arent any dual tap lands to help with the mana base
If you just want to crack packs with an eye towards value, Modern Horizons 2 is the best option because of how many powerful and expensive cards it contains, but you can still get burned if you open too many junk rares
