In person, you check the card yourself
If I've got Elrond and Herd Baloth on the field and cast the Cryptic Annelid I showed you earlier, I'll pay four mana, scry 1, scry 2, scry 3 and end up with an additional 17 power on board in the form of three 4/4 beast tokens, a 1 power Cryptic Annelid and six +1/+1 counters
Lucario can come out as early as turn three and its Fighting Coach ability adds 20 damage to all Fighting-type attacks against your Active Pokemon
If you find yourself running low on cards early, Mad Hatter, Gracious Host is a great way to build your hand back up
