Let's go over some basic deckbuilding theory [Supply Unit]

[Blake]

Once per turn, if a monster you control is destroyed by battle or a card effect: Draw 1 card.

 

This is a 3-0 card. You do not run just 2. Definitely not just 1.

 

At 1, it turns things into floaters, this is true. But if it made monsters gain that effect but didn't stack, it wouldn't be worth anything. It'd be a mediocre advantage maintaining card.

 

This card is good because in multiples it begins to + and restore your hand. It's no different than Reckless, in that regard. Would you ever run just 2 Reckless Greed if you had access to 3? Ever? No, so there's no reason to do the same with a card that is basically a neo-Reckless Greed.

 

If you're running 2, you can use the space better or open up 1 more slot for this. Always.

 

[Toffee.]

You know, if Konami wanted to be cool, they could "exclude" this card from the Structure Deck, and then release it elsewhere as an obligatory Secret Rare.
I mean, lets be honest: If this card were a Secret Rare, it could easily become a money card.

[OmegaWave]

It's an absolutely fantastic, splashable card. Staple? Depends on who you ask, really. Some decks simply cannot afford the space to it while others have had space open for a long time and just used fillers. Absolutely a 3-0 card.

But

 

But I want one

 

:(

 

OT: Obviously a very good card, and as you said, essentially a 3-0 card. Maybe with this, we can finally see the end of Hobaning.

[Wildflame]

This card is only abusable because it exists as multiples. It should be limited, and everything would be alright in the world.

[The Hounds Of Anubis]

Seriously, I hate seeing people play this in decks with no way to immediately trigger one of these. Those are the decks where it becomes a good card, since it immediately replaces itself at the very least, otherwise you let your opponent play around it. Playing this at a number other than 3 or 0 is about as irritating, actually.

[The Warden]

What I find most interesting about this card is how its level of effectiveness varies from deck to deck. Obviously destruction exists in every deck don't get me wrong, but this card really does reward decks that overdo it. Things like Fire Kings and Cosmic Dragons absolutely love this card to death. I mean seriously, get a Garunix loop off and you get a draw each turn on top of clearing the field. This card and factory actually made Scrap decks a legitimate threat.

 

But with Soul Charge being a thing, this card pretty much replaced Upstart as a matter of necessity since, let's face it: Soul Charge is bonkers, and giving your opponent one more monster is just asking for trouble.

 

Supply is by no means mandatory in every deck, save for those that can abuse it best or have the space. But until Soul Charge gets the inevitable ban, Upstart is still going to be booted out of decks out of necessity, rather than utility. We want our easy draws, but at least this card makes you work for... multiples are still f**king nuts though. I mean, draw 2/3 for losing a monster to destruction, just jesus christ.

[(GigaDrillBreaker)]

In the decks I have used it in (Hunders and Scraps) this card is incredibly powerful, pretty much being the upstart goblin that doesn't fuel soul charge. I haven't managed to drop multiples yet, but it is still incredible.

[Slinky]

I only run 2 in Hands because 3 clogged my backrow for me. Shame too, but, gotta do what you gotta do to make the deck happy.

... OR you could use common sense, keep the deck built as you should, and not blindly plop down 3?

 

You shouldn't run 2, ever

[Neutrality Man]

My Shadoll build runs this in 2 because 3 was TOO fast and uses the third's slot for a confusing RUM-LBF into C69.

 

Also this eliminates the need for NecroValley in any Deck that uses A Cat of Ill Omen.

[Airride]

Out of all the cards they DIDN'T make "The effect of X can only be used OPT", it's this.

SIgh.

[Delibirb]

I just realized I run this at 2 in my heavyweights o.o

I've actually been meaning to get rid of it because it makes big ben summoned by giant rat miss timing.

Don't they activate at the same time, though?

CL1 Unit

CL2 Rat

 

Rat resolves, SSs Ben K

Supply unit resolves, draws 1

 

Ben K's summon was not the last thing to happen, so it cannot switch.

[Toffee.]

That's what I thought, but Duston was thinking Rat misses the timing.

[Delibirb]

That's what I thought, but Duston was thinking Rat misses the timing.

No I wasnt. I said Ben summoned by a Rat misses timing if Supply Unit is in play.
