Lindwurm

When Lindwurm comes into play, connect all creatures in play together with the Lindwurm
and make it a X/X colorless Lindwurm creature
token, where X is the number of cards connected together. Each turn The Lindwurm attacks all
players. When the Lindwurm takes damage
remove one attached card and put it into it's
owner's graveyard. If there are no cards attached
to the Lindwurm sacrifice it.
The Lindwurm is indestructible.
