Bird Invasion 8 - Crazy with restrictions

Here is an approach as devised by my son on my profile using more common Cards apart from Necromancer Tower.  The Avatars chosen are ones without Frosthelm and Thor's Hammer.

Most Cards were not fully upgraded to mimic lower levelled Cards.  Hopefully, this setup may suit players with lower levelled Cards.

Those without a Necromancer Tower Card can swap it for Mana Tower.  In this case, just upgrade the Cardsharp facility only to speed up spell regeneration.

Enjoy.
