I love magic dice, mostly because when I play I play for fun. Randomizer is fun for that too, so I enjoy playing that as well.
As for practicality I love pairing stealth mine with a wings perk so I can drop mines on to unsuspecting players and activate it immediately for free damage.
I also like bear trap, on the right maps or with the right placement you can place a potentially lethal trap that can easily pick a free kill. It’s also funny but narcissistic to drop them on charge sodas or heart flowers.
There is super jump, which just launches you into the air a fair distance and there is spooky jump, which acts the same as normal super jump it causes an explosion a second after usage.
