changelings better be elementals...
or else Magic Online isn't working properly...
because I use Titan Changeling and the red hasted Changeling along with Avian Changelings in my 5 colour Elemental deck and I've paid for them with Smokebraider
A friend of mine manaburnt for 2 when he played a morphed warrior card with a pair of bannerets in play. So, while I'm pretty sure Magic Online gets most things right, I wouldn't stake any rulings based on them.
