Trample allows all excess damage a creature deals to be dealt to a player, making it even easier to use abilities that trigger when this happens, while reach allows them to block creatures with flying, which can be nasty if left alone
Each of the Crystals reduces the mana needed to cast cards in their respective colors by 1
So, instead of painstakingly finding the probabilities for each hand arrangement, you can find the probability of drawing the target card in 6 random cards (for the example with 2 copies, the probabilities are dhyper(0,2,58,6), dhyper(1,2,58,6), and dhyper(2,2,58,6) for 0, 1, and 2 prized respectively)
If you do this, make sure you keep the number of times youve cast each from the command zone clear for commander tax purposes
