When you have on your side of the field both meisei and his trap card bakura wont do nothing. In the end you try to end with 100lp and with the fusion monster. If not possible finish with chulain.
The reason for spirit invitation is simple. Free loss of 500 LP each turn. However I like burning land better because it destroys pre set field spells like Yami, mountain and harpies hunting ground
wait, shouldn't Balance work better with this?? I have 2UA so I don't need SpellReclamation. And if you remove the SpiritTrap then you can guarantee you'll always start with the Sealmaster trap.
