Trying New Spells in Soulkeep: Raining Cats & Venus FiendTrap

In My Soulkeep play today and first battle of the day with my regular tower I want to be more familiar with spells and I will try two of them that I rarely use and there are Raining Cats and Venus Fiend Trap and these are good spells with high magic damage and also acceptable range so in high fiends waves they may eliminate them all.

As for towers in this battle I have used for battles and these are regular ones and are Gloom Owl with about 60 Mana and Card Sharp with 70 MANA and My best Tower that I like which is Charnel pit with 120 Mana and Tarantula Loom with Good Mana to be used which are 50 Mana.

So Would it be a successful battle with these towers and Spells, For me in this battle I bet on the spells to do something for me in this battle and be able to eliminate as much fiends as they could so lets start and see what will happen.

In the first wave I used charnel pit and Gloom and card sharp as a danger triangular but as for these spells I want to use only venus fiendtrap as it can be used 4 times and the other one is used 3 times, Things went very well and I was able to beat the wave successfully losing only one card.

Really I liked the plan and update only card sharp to increase damage 100%
and used the second spell which is raining cat and things went so well also as I have lost no cards in this wave and the challenge will come with the other side as fiends will going in an empty way.

But wave 3 and 4 almost done with these spells as my impression for it is so good but I think their position should be near the gate to eliminate waves that pass from the tower but I know now to magic spells that are great.
