Myr Scrapling is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Sacrifice this creature: Put a +1/+1 counter on target creature.

Complete guide

Myr Scrapling is a versatile utility creature that proves even the smallest machines can have a massive impact on the battlefield. By sacrificing itself, this Myr ensures that its metallic essence lives on through your other artifacts and creatures. It is a perfect addition to decks that rely on +1/+1 counters or sacrifice synergies.

How it Works

Myr Scrapling features a simple activated ability that costs only the creature itself. By sacrificing the Scrapling, you can place a +1/+1 counter on any target creature. Because this is an activated ability, you can use it at any time you have priority, including during your opponent's turn or in response to a removal spell targeting the Scrapling.

Step-by-Step Resolution

First, you announce the ability and choose a target creature you control or even one an opponent controls. Second, you pay the cost by moving Myr Scrapling from the battlefield to your graveyard. Because the sacrifice is a cost, your opponent cannot respond to the sacrifice itself to stop it; once the ability is on the stack, the Scrapling is already gone. Finally, if the target is still legal when the ability resolves, the +1/+1 counter is placed on that creature.

Strategic Timing

Don't be too hasty to sacrifice your Scrapling! It can serve as an effective chump blocker. You can declare Myr Scrapling as a blocker against a non-trample creature, then sacrifice it before the combat damage step. The attacking creature remains blocked, and you still get to put a +1/+1 counter on another one of your units.

Common Mistakes

One common error is trying to sacrifice the Scrapling multiple times or for multiple effects. Once you pay the cost to activate its ability, it is in the graveyard; you cannot also sacrifice it to a different card like a sacrifice outlet at the same time. Additionally, remember that you must have a legal target to activate the ability; you cannot sacrifice it to nothing just to put it in the graveyard.

Interaction examples

Aerial Reinforcements

Ornithopter of Paradise

If your opponent casts a spell to destroy Ornithopter of Paradise, you can respond by sacrificing Myr Scrapling. By targeting Ornithopter of Paradise, you ensure that even if it survives the turn, it becomes a 1/3 flying threat, making it harder to kill in the future.

Fueling the Ballista

Walking Ballista

When you have Walking Ballista on the field, Myr Scrapling effectively represents an extra point of damage. You can sacrifice the Scrapling to put a +1/+1 counter on Walking Ballista, which can then be removed immediately to deal 1 damage to any target. This is a great way to finish off a planeswalker or a weak creature.

The Defensive Pivot

If your opponent targets Myr Scrapling with a spell like 'Exile target creature,' you can sacrifice the Scrapling in response. While the Scrapling still leaves the battlefield, it goes to your graveyard instead of exile, and you successfully place a +1/+1 counter on another creature, ensuring you get value from your card.
