What features in future arcanas would you like to see?

Title. They aren`t necessarily have to be super unique or original. Just something that you wish these arcanas need to have.

For example:

1)

Oracle Arcana should allow him to mark enemy heroes with a contract (identical to the one during TI10 battlepass where you placed a battlepass points bounty on enemy heroes) and getting X amount of completed contracts on invididual heroes grants the arcana a second style.

Additionally, whenever a contract is completed, Oracle has a specific phrase devoted to the hero slain.

2)

Enigma's arcana should have an similar effect to SF's arcana that when a hero is slain nearby, their remains are sucked into Enigma and float around in a glowing accretion disk until consumed.

Enigma's arcana should also have 5 different effects of the blackhole depending on the amount of heroes affected, just like Earthshaker's echo:

0 heroes, the hero signs and says something about himself failing, the effects aren't very impressive and it's just a blackhole with "suction" effect around it.

1-2 heroes, the hero says some more or less default response and the effects get more advanced. Instead of just blackhole, it also has a shining accretion disk around it, though its not very big.

3 heroes, the hero says some epic response and the sounds effects become global, at this point the blackhole becomes a quasar.

4 heroes, sounds and effects become even louder, scarier and global

5 heroes, some special phrase for that, maybe with TI + Astronomy reference with super scary loud and global effects.

Enigma's arcana should also have a lot of TI and Astronomy references in general.

Also, it would be extremely cool if Enigma's arcana revealed that Enigma true form was actually the thing that destroyed the sister earth Earthshaker was talking about when using his arcana and that Enigma's true abilities are expanding the more he consumes. And some responses including 5 clicks on hero ones or the ones when killing/greeting shaker would refer to it.
