I dislike the idea of having free powerful creatures. As high-costing as it is, decks based around this card would be perfectly OP.
At least 3 of the elements chosen have either hard-to-remove creatures, or high attack ones, not to mention those with skills that could cause havoc.
Only one or two of these in play, some defense, anti-PC/CC cards, and BAM, a non-viable deck made viable. Just... no.
Also, due to the continuous effect, I assume you meant to have this card be a permanent?
