Techno Nightmare

Flying, Trample
Whenever Techno Nightmare deals combat damage
to a player that player must discard seven cards. If a
player can only discard less than seven cards, that
player must mill the difference.
Techno Nightmares power and toughness is equal
to the number of swamps you control.
For each artifact you control Techno Nightmare
gets +1/+1 and "Ward {1}"
