This card is very subtle.
It is indeed strong, but to fully unleash its effects requires too many conditions.
The stacked Spell Cards need to be numerous enough.
There must be no Followers in your Follower Area.
The negative effect that allows the opponent to use Spell Cards without paying a cost means that from activation to becoming a Follower Card, this card's timeframe must be within a single turn. Otherwise, if facing a powerful opponent, this card could easily become their greatest help in defeating you.
And to fully exploit this card's effect in your own turn, it requires Spell Cards that allow card draws, and not just one.
Otherwise, even if you successfully transform the [Mobile Magic Academy] into a Follower, with only two to three thousand Spirit Value, it's still easy for the opponent to break it by combat.
