Defend Blood Queen Attack in Soulkeep Level 3

I was focusing on moonkarts in last weeks and I have seen a post about soulkeep that made me remember it and back to play and I have found that I am still at level three so I will have some attempts at it hoping I can pass it and moving to level 4.

At first I will have common cards to play with before I can rent cards and to see what will happen, when I opened the level I have found that Cauldron Dweller that cause the problem in this level with its armor and it needs a strong tower to face it and so I have to put Charnel Pit to it which is a strong tower and fast one also.

But Alone I think Charnel Pit wouldn't be enough to face Cauldron Dweller so I have used Charnel pit and close to it I have used Gloom Owl as a second tower and I will support them with a spell which is a stew of doom and things were going so well in first wave of this battle as I have managed to eliminate most of fiends.

In second wave there was a flying fiends that are in the second way and Gloom Owl was so good with them and be able to eliminate them and now I feel that I am gaining my experience back in soulkeep and feeling that I am strategic now and in the middle of battle thinking and trying hard to kill as much fiends as I could.

Before wave three started I have found that they will come from a third way and this way is empty as I didn't put any tower in it so I have put charnel pit and Gloom Owl so it can stop fiends but Till that Fiends were coming in numbers and also there was a problem that I have to focus on in next attempts that beside Cauldron Dweller there was also another threat from blood queen.

Blood Queen that yields so much bloodlings that were so fast need another strategy to be able to eliminate them and stop their threat.
