Rush of Knowledge (Onslaught/Legions/Scourge) The common consensus in Onslaught/Legions/Scourge draft was that you wouldn't want to play a deck with more than two colors, since there weren't many cards which allowed you to "mana fix" - that is, fetch a third color of mana
It has an insanely high attack stat of 2300, which rivals pretty much every other level 4 monster (and even many level 5 or 6 monsters) Your opponent will have to tribute summon or special summon from the extra deck to overcome this card
this turn, it cannot be destroyed by battle or by card effects
Because of that, its almost foolish to run spells in a Cascade deck that are reactionary, like counter spells (Arcane Denial) or protection spells (Heroic Intervention)
