Used to love Alrich, but Kelya is so much more valuable considering its price and versatility.
Based on which league you majorly play in, you can alter your strategies. Personally, I would recommend magic at bronze/silver league. With Oshannus and sometimes Abyss, it rocks. At gold or above, you can consider running a melee team with deeplurker, giant squid. Their synergy is awesome.
Tank suggestion: Diemonshark/Chain Golem (Chain golem at level 2 if you can afford it, I personally just rent it)
Output suggestion: Deeplurker, Axemaster, Abyss, Oshannus
Support suggestion: Venari wavesmith
