Selkie Hedge-Mage

Each of the triggered abilities look at your lands individually. This means that if you only control two dual-lands of the appropriate types, both of the abilities will trigger.

Both abilities are optional; you choose whether to use them when they resolve. If an ability has a target, you must choose a target even if you don't plan to use the ability.

Both abilities trigger at the same time. You can put them on the stack in any order.
