Evasion, Patience, and Trust
Enchantment
You may remove a creature you control from combat for every three creatures you attack or block with. If you do, put a +1/+1 counter on each removed creature and you lose one life.
At the end of combat, draw a card for each creature you control that dealt combat damage this turn.

Attack with 6 creature. After blocks, I may remove two of those creatures, lose 4 life and put a +1/+1 counter on each of them? The wording is mildly confusing
Also, that last line can be simplified to:
"At the end of combat on your turn, draw a card for each creature that dealt combat damage to and opponent this turn."
Creatures HAVE to attack in order to deal combat damage.
