- 26 April 2014If Riptide Chimera is the only enchantment you control when its ability resolves, you must return it to its owner's hand.
- 26 April 2014If you control no enchantments when Riptide Chimera's ability resolves (perhaps because Riptide Chimera stops being an enchantment for some reason), then nothing happens.
