Enchantment
Oracle Text
Whenever an opponent casts a spell, you may draw a card unless that player pays {1}.
Watch Out
Opponents choose whether to pay {1}Common Misplay
When an opponent casts a spell, Rhystic Study triggers. The opponent may pay {1}. If they don't pay, you draw a card. This is a 'may' ability for the opponent — they are not forced to pay. You must announce the trigger.
Triggers on every spell, not just the first each turnWatch Out
Unlike some similar effects, Rhystic Study triggers on EVERY spell an opponent casts, not just the first one each turn. In multiplayer, this adds up quickly.
