It can work with 1 or 2 burning lands, but because of all the Harpies in plat 2 I started running 3. I'm debating on changing the embodiment for something to counter relinquished. But it needs more testing.
3 x Attack and Receive should be in any Chain Reaction deck. Attack and Receive do 700 damage each, plus 300 damage for every ATK+REC in graveyard; so, that's 3000 damage if you play all 3. PLUS, 200 damage for every trap card played via Chain Reaction = 3600 damage!
this deck seems to have a good potential, I was able to reach 4 stars level on kaiba cup effortless while I lacked some cards like curse of anubis or windstorm of etaqua. It isnt often played but I recommend it
