Silo

Description
Summon a missile silo of which will launch a nuke, detonating and damaging all Beings on the battlefield. The summoned structure has 300 hitpoints.

If the summon structure is destroyed before the missile hit the ground, the attack will be cancelled and no damage will be dealt.

Unlike the hazard structure Silo, the explosion from this spell does not harm the player.

Strategy and Synergy
A costly spell that can be a last-resort cast in some circumstances due to the high damage and guaranteed hit chance. In many aspects, Silo is the version of, except that it deals slightly reduced damage for the ability to be cast many times in the match and landing on all tiles regardless of the player's position.

The major disadvantage are its expensive mana cost, rarity and delayed action (slowest in the game, at 12 seconds), taking twice as long as, but being overall more manageable than the aforementioned EXPLOSION! spell since Silo lacks the "resting period" and don't the player.

However, Silo can be used as a melee-range nuke, bypassing the 12-second delay, using cards such as or  to bring an enemy to the front-most row then casting Silo on the tile they're pulled to. (As a bonus, destroying or killing the entity on an occupied tile will still summon the Silo as though it wasn't occupied at all.)
