4 Shadow Summoners
A stepping stone to Ocean Mage Summoners is using Kindred / Varus / Malzahar while waiting for Yorick / Brand / Annie. This middle step can pivot to Ocean Mage Summoners or Shadow Summoners. The latter is slightly weaker late game (unless you high roll Shadow Lux) but requires much less luck to get strong since the units are less contested. Kindred and Malz are your carries here. Try to 3-star them if possible. Zyra can be replaced by Yorick. Yorick synergizes with Malz since he can ult Malz's minions. Alanzq, a top EUW player, loves to run Shadow comps.
