Mind burrower discussion

Of all the latter suggestions, I still like the larval/gain ability change the best. Simplest and effective. You lose the ability to undizzy them with creatures, yes, but that doesn't seem like too big of a deal. OTOH, you can use other spells to keep them alife (equip armor and so on), unlike straigh inmunity.

Changing costs has been tried, and it just makes the combo more or less common. Some adaptive costs might work (take damage equal to the target's attack, pay half the target's cost, etc), or some sort of compensation (oponent gains mana equal to the target's sac). But it seems that a turn delay ought to be acceptable, given the fact that it was like that before.
