Sweeping Trio - "Reaper the Soul"

[KoolGoldfinch]

So, I got this idea from the mythical creatures called "reapers".  Basically, they are the ones that come to collect your soul and basically kill you when you die.  They are not able to be seen by normal people and are usually under the command of Death himself.  However, in one episode of "Supernatural" (yes, I'm using a pop-culture idea for a card here, however these cards are in no way pop-culture related) a regular person was able to use a magic stone to control a reaper and get it to do her bidding.  It got me thinking, how powerful could one be in Duel Monsters?  So, I based the reaper around being able to clear the field of Monsters' souls while in no way harming either player.  I tried to keep this set very balanced, and you NEED to play these cards right in order to get and maintain full use of them.  These are some of my favorite cards I've ever made, and it all came out of me looking through card artwork and saying, "Hey, that kinda looks like a reaper... hmm..."

Anyway, check 'em out!  I'm open to critique and OCG-corrections.

 

[spoiler='Host the Spirit Caller']
LORE:
When this card is equipped with "Death's Stone": This card is not affected by card effects (except its own) and cannot be destroyed by battle (damage calculation is applied normally.) If this card is sent from the field to the Graveyard by a card effect: You can banish this card; add 1 "Reaper the Soul" from your Deck to your Hand.[/spoiler]

 

[spoiler='Death's Stone']
LORE:
This card can only be equipped to 1 face-up "Host the Spirit Caller" you control. As long as this card is active on the field: Neither player can Special Summon Monsters from the Graveyard. If this card would be destroyed: You can discard the same type of card that would have destroyed this card; negate that card's effect and banish it. You can only control 1 active "Death's Stone" at a time. At each of your Standby Phases: Either pay 500 Life Points or destroy 1 Monster you control, and if you do not: Banish this card.[/spoiler]

 

[spoiler='Reaper the Soul']
LORE:
This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except by its own effect. If you control 1 face-up "Host the Spirit Caller" equipped with "Death's Stone": You can Special Summon this card from your Hand. If you do not control an active "Death's Stone", this card cannot declare an attack. If you control no other Monsters other than this card: Banish this card. This card is unaffected by all card effects (except its own, "Host the Spirit Caller", and "Death's Stone") and cannot be targeted as an attack target. Any Battle Damage involving this card becomes 0. Any Monster that battles this card is banished regardless of any card effect. When this card leaves the field, banish it.[/spoiler]

 

Again, the idea comes from needing the stone to control the reaper in the first place, so you need the stone in order to use him to his full potential.  Each of these cards is key to using this strategy and while not totally impossible, I feel it's not too OP, either.  Please let me know if I struck a good balance here!  I really love these cards!  BTW: I made Reaper holo myself ;)
