Pivoting

A pivot is a change of line made before the line has failed, with gold in hand. A "pivot" made after a failed rolldown at 4-2, with 8 gold and 30 HP, is not a pivot; it is a slow 7th. The skill is not knowing how to change comps (any Emerald player can do that); it is reading, at 3-2, that the line you like is not available to you in this lobby, and being fine with that.

Reading contest

Contest is arithmetic before it is a feeling. Each unit has the copies listed in the pool table; every copy on another board or bench is out of your pool until they sell it. A 4-cost carry with two other players each holding two copies has lost 4 of its 10 copies before your rolldown starts; your per-slot odds at level 8 drop by roughly 40%. A 2-cost reroll unit with two other players each holding a 2-star has lost 6 of its 25 copies and, more importantly, both of those players will buy every copy they see for the rest of the game.

The reads, in the order they become available:

• 2-1. Contest is soft. Pairs are everywhere because everyone buys pairs. Note who holds what; do not act on it yet except to avoid taking a trait augment for a trait two players are visibly on.
• 3-2. Contest is real. A player still holding your unit at 3-2, with an item on it or a trait around it, has committed. Count them. One is normal for a 4-cost line and a pivot signal for a reroll line. Two is a pivot signal for either.
• 4-2. Contest is final. If you learn about it here you are learning it from the rolldown you just lost. Never let the first count happen at 4-2.

Contest is also asymmetric: it matters who is ahead. If the other player has the 2-star already and you have a pair, they are not contesting you, you are contesting them, and the pool math says you lose. If you have the 2-star and they have a pair, hold your line and they will pivot off you (or should).

Flex openers

A flex opener is a stage 2 and early stage 3 board that wins or nearly wins fights without committing to a final comp. Its purpose is to hold the decision open until 3-2, when contest is real and the augment is known.

The shape of a flex opener: the strongest 2-star units available regardless of trait, a frontline that holds, one itemised unit whose item is broadly useful (a flat tank item, a generic damage item), and pairs on the bench of any unit that appears in more than one endgame line. What it is not: a stage-2 version of a specific comp with 1-star placeholders for units you hope to hit.

The reason flex openers are correct at Emerald and above is not that commitment is bad; it is that early commitment is expensive in exactly the currency you cannot recover. Committing at 2-3 to a reroll line means buying copies at 2-5 and 3-1, taking the trait augment at 3-2, and holding 6 while the lobby levels. If two other players are on it, you find out at 3-5 with a bench of 1-costs and no HP to spare.

The cost of flexing is small and specific: a couple of bench slots and 4 to 6 gold of pairs you will sell. The cost of not flexing is a game.

When to abandon a line

There are two abandonment points, and they are not equally good.

At 3-2, with gold in hand. This is the pivot. You scouted, counted two committed players on your line, and you still have 50 gold, a flexible board and 70+ HP. You sell the pairs that only belong to the contested line (usually 4 to 8 gold of loss), keep the units that fit the second line, and take the augment for the board you can actually build. Nothing about your econ plan changes; the target of the rolldown does. Done here, a pivot costs almost nothing.

After a failed 4-2 rolldown. You rolled 50 gold at level 8 for a carry three players held, hit one copy, and now sit at 8 gold and 40 HP. You can still change comps, but you are changing to whatever the rolldown accidentally found, with no gold, on a board that lost two more rounds while you rolled. This is not a pivot; it is damage control, and its outcome is usually 6th. The correct response is the top-4 play: slam everything, 2-star what you found, position defensively.

The rule is: decide at 3-2, or accept the line. The middle, "I'll see how the 4-2 rolldown goes", is choosing the second abandonment point while pretending you have not chosen.

Signals that it is time, at any round:

• two or more committed players on your carry (counted, not felt);
• a committed player who is ahead of you on the unit (their 2-star to your pair);
• your components cannot build the line's core item and the carousel did not fix it;
• the augment you were offered makes a different line clearly stronger from where you stand.

Signals that it is not time, despite the temptation:

• one contester on a 4-cost line (normal; the pool is deep enough);
• a bad shop this round (variance, not information);
• the stats site says your comp is "B tier" (irrelevant to the board in front of you).
