He only needs one draw to be good, two makes him great but you are probably averaging 0.3ish draws per Sram cast in a deck with 3 targets
Where the binomial distribution tells us the probability of getting a specific number of successes with replacement (i.e., equivalent with shuffling your deck, revealing the top card, noting whether its a land or not, then shuffling again and repeating), the hypergeometric distribution takes into account that card draws are, in fact, not independent (i.e., telling us the probability of getting a specific number of successes without replacement, where cards arent reinserted into the deck after being counted as a success or not)
I have a mask to select the corners and delete them in a photoshop action - then the key is to save as PNG (which is a fair bit bigger, but worth it) then rename to jpg to match the expected forge filename (it might be possible to change the forge filename to expect PNG - I haven't looked - I guess they are defined just in a text file somewhere)
There are a lot of very good cards in the Modern Horizon 3 expansion, and many of these cards synergize with having creatures in the discard pile
