Volcanic Eruption is a Normal Trap with two very specific activation restrictions: End Phase only and while Jurassic World is in play.  Jurassic World is a mildly disappointing Field Spell.  I don’t consider Field Spells to automatically be a waste, and further more I am much more forgiving of them being mere stat bonuses than some others I know.  The reason is my play testing has taught me that sometimes brute force wins.  The +300/+300 bonus Jurassic World gives will put a Dinosaur over most supporting monsters and surpass all but the bigger beatsticks of the relevant level.  For example, Hyrdogeddon now ties Breaker the Magical Warrior when he has a Spell Counter and can easily run over him if he doesn’t.  Sabersaurus can mow down a Cyber Dragon, and Dark Driceratops can dispatch a Monarch.  Since it affects DEF as well as ATK, Black Stego gains the ability to shrug off any sub-Monarch attackers (other than attack/effect kills).  However, in most cases even if one lost Jurassic World while battling, the opponent is at best forcing you to break even.  Better “pressure cards” exist, or so I am repeatedly told.  I understand why cards like Swords of Revealing Light, Messenger of Peace, or Wave-Motion Cannon are used.  If the opponent ignores them, they are incredible, ergo the opponent is often forced to use up valuable S/T removal on them instead of things like your Traps.  The three I listed, at least at one time valued by many for this function, are rarely much help to a core Beatdown strategy, and are sometimes even less useful than a simple attack boost.  Swords of Revealing Light lasts three turns at most (without additional support), Messenger of Peace has a (minor) maintenance cost or else is meant as a single turn stall, and Wave-Motion Cannon takes time – time enough for you to lose before its worth launching and before they need to nuke it.  Sometimes, the simplest choice is the best.  A note of warning, as my “meta” consists mostly of casual play with friends, it is quite likely the pressure card tactic is waning (or has ceased) being relevant for big, tournament level play.  Then again, Dinosaur decks aren’t so great for that anyway. ;)

 

So, now that I’ve covered why a Dinosaur deck would include Jurassic World (other than to use Volcanic Eruption), the reason to include one of these is simple: even though you’ve got to do it probably the worst time to do it, it clears the entire field.  All monsters and Spells and Traps on each side of the field.  Since Jurassic World has to be in play, obviously this means at least a -2 for you.  So, how likely is your opponent to have at least three cards in play?  Two cards in play, letting you break even in terms of card count at least, is common.  A Spell or Trap and a monster are generally what one assumes an opponent will have in play.  From there, it’s less common but still fairly likely they’ll have one other S/T or a second Monster, though the second Monster is something along the lines of Cyber Dragon, Spirit Reaper, or Sangan.  Other than Sangan, I wouldn’t mind blowing up things like the other two.

 

This would still be kinda desperate, but fortunately there is an obvious combo for all Volcanic Eruption: Babycerasaurus.  When that Monster Card is sent to the Graveyard by an effect, it lets you search out a Level 4 Dinosaur from your Graveyard.  So just slag the field and get a solid attacker.  That is a lot of effort though unless you’re winning the game with the move (which you won’t be).  It is okay if you’re setting up for, if not a win, a major threat that can win you the game next turn.  That would be Tyranno Infinity.  That is a Level 4 Dinosaur that can get really big, really fast with a little help.  And that is where this card finally finds its niche: setting up Dinosaur combos.  I can only think of three specific low level Dinosaur combos that might be worth using (but probably not in the same deck): Tyranno Infinity, as I just stated (and will discuss in detail in its CotD tomorrow), Black Ptera OTK (which isn’t so much a deck as a handy combo one could add to another Dinosaur-deck), and even Water Dragon decks (Jurassic World would power up the two components to decent levels).

 

So in the end, this card just barely seems worth running in one specific Dinosaur deck, Tyranno Infinity Rush, which can consider one or two copies of this to make it setting up the kill easier: even with a turn to build, there’s only so much your opponent can do, and Babycerasaurus with this will get Tyranno Infinity into play that much easier.
