Ddq new survival mode

Ddq could be a place were any crazy challenge would be posted so I have this one.

Any player no matter the time it has playing may pick this challenge. The challenge consist on picking 1* 2* 3* 4* hero's against X hero. (once someone said on a tread 300 juggernauts) If you pick 1* survival well you will be using 1* hero's until drop dead against X hero. X hero will start at level 1 and increase level each time he dies, 1,2,3,4,5 depending the node challenge he enter. Prices will go accordingly how high the player scale.

1 - Players may pick the tier hero 1* 2* 3* 4*, but this hero's are not meant to be mixed between tiers.
2 - The tier hero's will be random picks with the option of roll one champ for 2 times.
3 - Random teams also avoid game to became monotonous, aca shield masers.
4 - The amount of rounds could be endless and may have a score ranks for braggers lol.
5 - Players need a roulette for reroll (better than ddq 2* biased roulette)
6 - When you loose, gg until the next time.
7 - The survival mode can come once a week perhaps?
8 - Prices should stay the same on every node but vary in the proportions of kills and tier.
9 - 100 iso per dead X hero would be nice price but this may vary.

This would be a good way to use hero's that old players may not use anymore and new players have something challenging for themselves too. Even ppl may start collecting all hero's (with exception of bag's, sentry or hulk weinner) Also remember that players may pick a tier they like, for me 3* is the more fun and this also may add variety. Btw game could be a 300 juggernauts slauther, hes balanced board shaker and suicide.
