Willbreaker

[Oldschoolmtgnoob]

I'm looking for a good synergy with {willbreaker}. Specifically something that fires off every turn. Like "at the beginning of your upkeep ____ does _____ to target creature.

Just thought this...{kiora, the crashing wave}. Other P dubs I'm sure

[redwolv]

Any specfic format? Or in general?

 {Citadel Siege}, dragons mode. Steal one every combat.
There's  {Conjurer's Closet} with {dragonlord atarka} if you really want to go wild..

EDIT:  {Ral Zarek} Seems potent too. Steal up to two with +1. And {koth of the hammer}'s ultimate, while not free, is just badass. Tap a mountain to take control of a creature, destroy it if its toughness is 1.

It's not every turn but {descent of dragons}+{willbreaker} is just evil

{Lorthos, the Tidemaker}
Swing, target 8 dudes, don't pay 8 mana, steal 8 dudes.

Dudes.

If you don't pay the 8, you don't get the dudes...

Whenever creature becomes the target. You target, then on resolution decide to pay or not. You get the dudes.

If you don't pay the 8, the ability doesn't go off, and you don't get to target. I'm not saying it doesn't work, just that it costs 8 more than you thought it did...

"When "this creature" attacks, you may pay 8. If you do...<= key wording here

{throwing knife} has the exact same wording, yet the ability and its targets are put on the stack when you attack. The creature is targeted wether you sacrifice or not.

EDIT:

Note that this is not worded: "whenever you attack, if you pay", so the rule of the intervening-if clause does not apply. This one does, however.
603.5.: Some triggered abilities' effects are optional (they contain "may," as in "At the beginning of your upkeep, you may draw a card"). These abilities go on the stack when they trigger, regardless of whether their controller intends to exercise the ability's option or not. The choice is made when the ability resolves. Likewise, triggered abilities that have an effect "unless" something is true or a player chooses to do something will go on the stack normally; the "unless" part of the ability is dealt with when the ability resolves.

[Double-O-Scotch]

The ability goes on the stack, but unless you pay you can't TARGET. Which is required for willbreaker

But you pay when the ability resolves, same mechanic as with the knife. And you choose targets as you put the ability on the stack, not when it resolves (which is when you pay).
I had the issue with knife & WB in duels:origin. When I wanted to file a bug, I noticed it was the proper ruling.

[Double-O-Scotch]

You're missing my point. If you don't pay, you don't target. If you don't target, willbreaker doesn't trigger.

Willbreaker doesn't trigger for lorthos's triggered ability, it triggers when you target.

Now you can word it any way you want but that's what it really boils down to.

Lorthos, the freshmaker

When Lorthos attacks you may pay 8, if you do, tap up to eight target permanents. If you don't, target those creatures anyways but they are only targeted, with no effect.

See? I know you really want it to work, (great idea!) but it makes no sense. None.

I've played magic a long time, and all abilities work like this. Cost. Effect. You pay the cost, you get the effect. Why does this debate sound more like a legal loophole in court than a game mechanic?

That's activated abilities you're talking about.
{8}: tap up to 8 creatures. Activate this ability only when Lorthos is attacking.
Magic's comprehensive rules can be a lot like Law, but it isn't my intention to make you feel like having one. Brokenness is often based on loopholes in the rules, to be honest. I doubt  {Balustrade Spy} was designed with the idea of self-milling your entire deck.

Yes, WB triggers when targeting, and that happens when you put an ability on the stack.
However: let's get back to other combos with WB, and let this one be, for the sake of argument.

I like {confusion in the ranks}, though it does need some hexproof or shroud on WB to be effective. (You steal the targeted creature if it's not already yours, when you cast a creature you counter CitR's ability because you control the targeted creature when it resolves. End result: steal all the creatures.)

[Double-O-Scotch]

Maybe I'm just too much of a purist. That's not how I read it on the card. That's clearly not how it's supposed to work. And you should never get an effect that requires some sort of criteria when said criteria has not been fulfilled. That's just common sense. There's nothing in the comprehensive rules that says I can't reach across the table and literally slay my opponent, but we abstain because it's just sort of accepted that you don't do that.
