Fling is a simple effect that tells a lovely little story
Still, a near-guaranteed Clue every turn starting on turn 2 sounds appealing, so maybe theres something to this transforming planeswalker
Though value is always tempting, dont be afraid to play these as simple taplands when your hand needs it Towns Final Fantasy also introduces a new land subtype called town. Theres nothing intrinsically special about towns, though there are several cards that care about them specifically (which is actually UGs focus in Draft)
The reason this ability is so powerful is that if you have a way to untap an artifact, such as a Voltaic Key, youre then able to draw multiple cards a turn
This is, in fact, probably the most tame thing you can do with the card
Ratcatcher is also an important payoff for getting the best rats out of your deck quickly
