The Alpha "killer" cards are not yet available to quadruple the output of trophies.

I looked at the top rewards for trophies myself, wondering if the top players would get them. Not looking good considering that the top reward is 2 million and the top score is 334k. However, when you take into consideration the release of the new killers, as well as the fact that most people are hoarding their radars, 2 million seems more viable.

Besides, Nutaku will just say "Buy more eGatcha tickets and glasses." This is the event that cares the least about free players.
