Bring to Light is a pretty good way to get
Horde of Notions or
Maelstrom Archangel into play reliably, but I don't think it works so well with the Evoke elementals, since it looks only at their mana value (which in a lot of cases is greater than 5 and cannot therefore be found, even with full domain) and not any alternate costs you could play them for.
Maelstrom Nexus + Evoke is pretty good, but there are a lot of high cost elementals here and only two of the Nexus; maybe either more Nexuses or some way to search them out?
