When this creature enters,
open an AttractionA player may open an Attraction only during a game in which that player is playing with an Attraction deck (see rule 717, “Attraction Cards”).
To open an Attraction, move the top card of your Attraction deck off the Attraction deck, turn it face up, and put it onto the battlefield under your control.
An ability which triggers whenever a player opens an Attraction triggers when that player puts an Attraction card onto the battlefield while performing the instruction in the above rule. If an effect prevents that Attraction from entering the battlefield or replaces entering the battlefield with another event, that ability doesn’t trigger. (CR 701.51). (Put the top card of your Attraction deck onto the battlefield.)
At the beginning of your end step, if you control three or more Attractions, you draw a card and you lose 1 life.
