This is what you should do:
Sell Andsom (Cyan helps this deck with high solid power like all the others.) From pirans you would get 1700, you spend that on Roots, then you spend about 1100, you have an extra 600 to your 1k budget, sell your Cyan and buy Tyd.
The cards you need from Piranas on your budget are:
Don't get caught up with SoA ability being needed, Spycee is just a bad card with his 5 power and low damage.
You could build a very able Roots/Piranas deck on your budget, for example:
Kristin 4* (conditional SoA, but /much/ more potent than Spycee)
Lots of high power, SoA and SoB mix, decent mix of abilities, and a very potent deck for very little clintz.
