Also,

Defence Builders
Creature-Human Soldier
A deck may contain any number of cards named ~
At the beginning of your upkeep, if you control twenty cards named ~, you win the game
0/1

Also the first two cards from the random ideas threads (rebalanced to fit your suggestions)

Seasoned Soldier
Creature
If ~ is attacking, it gets +1/+0
If ~ is blocking, it gets +0/+1

And

Improving Spellcraft
Instant
A deck may have any number of cards named ~
Draw a card for each card named ~ in your graveyard

you forgot the power and toughness

And a creature type.
