To summarise the combo: Cast Threefold Thunderhulk, which makes you three gnome tokens Copy it with Saheeli, Radiant Creator, which makes 8 more gnomes tokens As the copy of Threefold Thunderhulk's base power and toughness is now 5/5 and enters with three additional +1/+1 counters Attack with Threefold Thunderhulk and make another 8 gnome tokens You would be left with the original Threefold Thunderhulk as a 3/3 and nineteen 1/1 gnome tokens There is a little bonus to the Threefold Thunderhulk, as it has one more ability
This is a really useful tactic that could get you all the Energy you need in the format where it was legal
Last but not least, Crystalize is a powerful unique ability, making it even more certain that you can target and destroy unwanted Evasive characters before they cause too much damage
