6G Sky Drop Weight Limit

In game it just says "But it failed"

Veteran Padgett (tester) and I both agreed it should let the user know why it failed.

```
Start of turn 1
Smeargle used Sky Drop!
But the foe's Groudon is too heavy to be lifted...
```

Also, behavior regarding Red Card/Eject Button and Knock Off are correct. Removing comment that states there is an error.
