Thank god for the lightspeed change.

They swapped them. Ewer and Spire used to double duration of the next card and Arrow and Spear would make the next card aoe. Now Arrow and Spear double duration and Ewer and Spire will make the aoe. Dunno why they swapped it but I guess since Ewer and Spire are so useful now there's no reason to RR them away.
