Soulkeep - What Towers for Level Five?

Level five is full of new things that I have to be familiar with to be able to pass this level, I have checked league to see how much fiends should I kill and I found that I have to kill 1500 Fiends and this means for this level which is 8 waves that each wave I have to kill 200 fiends and this is what I have never faced before so it is time to choose a good towers to start the level with and to be able to pass it.

At first I will try some common cards which proved their ability to smash fiends down in first levels and especially for level 4 that I have passed them with these common, so first tower will be definitely Gloom Owl which is very amazing and have a good ability to kill low HP Fiends that are passing in the field.

Second One will be fountain of terror which have a high range and with it we can cover a good area and possibly two ways that fiends are passing in and the third one will be slime lord and I thought of it to because of we have more than 1 thousand fiend to eliminate so we have to slow them up so towers can take a chance to get rid of.

And Final tower will be card sharp as its magic helping in killing more fiends and also flying ones and this is what I am seeking for to have an advantage for this level against fiends, I think I must have upgraded Card sharp towers.

For Spells I will have three different spells that will be available for me in this level and they are stew of doom and raining cats and Gear Grease as I want to enhance the fire rate of my towers.
