I think that will happen easily, and this is a solid buy for me at $4
Traditionally, we just raise the mana cost, but here's the problem
If you put a Trickster's Elk on an opposing creature to shrink it down to a 3/3, and then the creature dies later on, you are the one left with the original 3/3 Elk on the battlefield, not your opponent
They are not spells - you don't need to pay mana to put them into play, and they cannot be 'countered' by counter spells
If the spell or ability has damage divided as it was cast or activated, the division can't be changed (although the targets receiving that damage still can)
But something went wrong, and we ended up with this less than ideal result
