Blake, Evil Scrum Master

When Blake enters the battlefield, create an
empty data set and a 1/1 legendary black software
creature token named Benjamin.ai.
Whenever a player casts a creature spell add it's
creature types to the data set.
Software creature tokens you control have
+1/+1 for each entry in the data set and have
protection from creatures of all types listed
in the data set.
"This data is a mess!"
