-1 Plant Food Chain
+2 Pollynosis

you need draw power, and ivy shackles with fragrance storm is amazing. Destroy one of your opponents monsters and draw 1 card? And if that card you drew was a plant type monster, you can draw one more card? I'd call that great. Copy plant is yet another great card when used with ivy shackles, as you can select your opponents monsters as well. Gravirose can be an amazing card too, and can easily count as your foolish burial but has much more potential.

This might change this up quite a bit, but these cards are definitely suggestions you could use if you want
