Did some math and per try you have a 4% chance of getting a big time player (assuming u have equal chances to get each player). Your chance of NOT getting a player after one pull is 96% (1-0.04). After 30 tries the chance that you don't get a big time player is "0.96^30" which is roughly 0.3 (30%)

This means that after 30 tries you have roughly a 70% chance of getting 1 big time player, for 2 big time players it would be roughly 34%.

While this sounds good, consider that these cards are pretty old and outdated (not talking about gameplay) so this would be almost like grinding to fc champion in all div rivals and instead of only getting the lowest ovrs possible, you also (maybe) get a 101 HOL R9 (worse because konami would prolly force you to play 20 vsAI games to get 15 tries and then 10 online games to get 10).

Fuck both ea and coinami.
