I think, this is not a card for rainbow decks or speed decks. If you play these decks, it could be underpowered for you.
It´s useful on: Arctic Squid, Purple Nymph, FFQ, Steam Engine, maybe Lava Golem.
Creatures with high skill costs, or skill costs which are not your color.
It can be good in duo or mono- decks.
You can e.g. make an Entropy deck, which can use the skill of the Fallen Druid. Or Air deck with FFQ.
The card doesn´t need to be more expensive.
And drawing cards is
, and nothing for "other".
