Alongside Underworld Breach, Invoke Calamity gives red Spellslinger decks a great deal of redundancy when trying to pull off those multi-spell turns
There have been so many games in which I am either throwing down sacrifical planeswalkers to try and stop them eating my other cards or throwing out artifacts and enchantments in the hope that they will be tempted to destroy them rather than attacking my planeswalker
Greninja BREAK took second place in the Masters Division at last years Pokemon World Championships, and even though a whole years worth of new cards have come out since then, it still looms over the field with its slimy scarf-tongue
It offers a double trigger on your creatures enter the battlefield abilities, a way to cheat out high-cost creatures, and an opportunity to bypass the obstacle of summoning sickness
What makes this deck extra strong is the utility provided with lands like Dakmor Salvage with the dredge ability, a Drownyard Temple that you can sacrifice over and over again, Field of the Dead that starts producing 2/2 zombie tokens in the late game and Glacial Chasm
