Bitter Work's first ability has you draw just one card per player you attack with a creature with power 4 or greater, no matter how many creatures with power 4 or greater you attack them with beyond the first.
Whenever you attack a player with one or more creatures with power 4 or greater, draw a card.
Exhaust — : Earthbend 4. Activate only during your turn. (Target land you control becomes a 0/0 creature with haste that's still a land. Put four +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped. Activate each exhaust ability only once.)
