Gumble's upgraded passive ability should be reworked, as the current one is boring and a tad problematic and not having much going on for the wow factor or mechanics.
New version should be: Can revive if nothing on top.
How this works: if Gumble is killed, there will be a puddle plus the drop on top.
The revive happens when Gumble will have his turn, as a question mark icon will be in the unit queue, with "Gumble" as status, highlighting the puddle on hover and vice-versa (hovering on the puddle will indicate the avatar, just like it happens with any unit.
So in order to be able to kill Gumble:
Either do it fast until ability is upgraded or leave something on top of the puddle, like a unit or drop or destroy the puddle altogether.
