R&S Chansey ex using Healing Egg

[Prof. Douglas Zuver]

Chansey ex (Ruby and Sapphire card # 96)

Healing Egg
Remove 2 damage counters (1 if there is only 1)
from each of your Pokemon. Remove no damage
counters from Chansey ex.

Double-edge 80
Chansey ex does 60 damage to itself.

Things are fine if we only have one Chansey ex on
the table. Healing Egg heals everyone but the active
Chansey ex.

But where there is one Chansey ex, there is bound to
be another in the deck somewhere.
And sooner or later somebody will put the hurt Chansey ex
on the bench, and move a new one out front and use
Healing Egg. Then their opponent will raise their hand,
call Doug over and say "Chansey ex can't heal Chansey ex."

(At that point Doug will roll his eyes and ask for a Lava Cookie)

Anyway, there are at least two ways to look at this:

First, that the words Chansey ex is the self referencing rule,
and it would have been better written as:

Healing Egg
Remove 2 damage counters (1 if there is only 1)
from each of your Pokemon. Remove no damage
counters from THIS Chansey ex.

.........................................

Second, that Chansey ex simply is unsocial and cannot
heal ANY Chansey ex on the table.

Thanks,
Doug
