A recurring problem with Magic: The Gatherings Secret Lair drops, in recent times especially, is that the cards in each drop arent worth the $30 asking price
As you have access to the Ink ramp of Sapphire, try upping the count of those cards
No more subjective descriptions like "near mint" or "excellent" that mean different things to different sellers
Caradora, Heart of Alacria Hitting just mounts (and vehicles) makes Caradora, Heart of Alacria rather narrow, but the generality of the +1/+1 doubling ability makes up for it
The card only costs three ink to play, and unfortunately, only has four defense, which will make it a quick target for opponents
In Magic's case, this is usually because they cost too much, so by the time you can cast it, you would already be ahead in the match
