Battlegrounds Blood Gem Hardlock

I played Death Speaker Blackthorn and started hoarding blood gems from the start.
But when your hand is full of blood gems and you have no friendly creatures, you can no longer do anything. There is no hand room to buy a creature, and there is no creature to play the blood gem on.

I assume this could happen to anyone if a Razorfen Geomancer is your last creature sold and that gave your 10th blood gem.

I can avoid it in the future knowing that, but it was a bummer.

This is only a issue once, you will never do it again

Only thing I can agree on here is that it doesn’t make sens that you can play spellcraft spells on tavern minions but not blood gems
