Think I might have underestimated the power of Shotlocks...
This is sudden, I know, but new rule: you can't learn a Shotlock unless you know both abilities on the
Command Meld. In the case of Meteor Shower (the Shotlock Card went for) that would be either Thunder/Fire, Thunder/Strike Raid, or Zero Gravity/Blitz.
Again, I know this is a sudden change, but it struck that there are powerful Neutral Shotlocks that, according to the previous ruling, could be learned as early as right now, which didn't seem balanced when I thought about it, hence the knew ruling. Sorry for any inconveniences that may cause anyone.
EDIT: Changed Jared's Vortex to Sonic Blade. No more changing the Minor Ability now, I promise. xD
