Tandem Tactics 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
Up to two target creatures each get +1/+2 until end of turn. You gain 2 life.
Complete guide
Tandem Tactics is a versatile white instant that offers a defensive boost and a touch of life gain to stabilize your board. Whether you are aiming to survive a combat phase or simply looking for a small health buffer, this card provides valuable support for up to two of your creatures.
What It Does
Tandem Tactics allows you to target zero, one, or two creatures on the battlefield. Each target selected receives a +1/+2 power and toughness bonus until the end of the current turn. Regardless of the number of targets chosen during casting, the spell also includes an effect that grants you 2 life.
Resolving the Spell
The resolution process depends heavily on your choice of targets. If you cast the spell with zero targets, it resolves and you gain 2 life immediately. If you choose one or two targets, the spell checks if those targets are still legal upon resolution. If at least one target remains legal, the spell resolves: the legal targets get +1/+2 and you gain 2 life. However, if you chose targets and all of them become illegal (for example, they leave the battlefield), the entire spell is removed from the stack and you will not gain any life.
Common Mistakes
A frequent error is assuming you always gain life regardless of what happens to your creatures. Because the life gain is part of the spell's resolution, the spell must resolve for the life gain to occur. If your opponent uses a removal spell to eliminate your only target in response to Tandem Tactics, the spell 'fizzles' (is countered by game rules), and the 2 life is lost.
When to Play It
This card is best used as a combat trick to help your creatures survive blocks or trade up against larger attackers. Since it provides +2 toughness, it can often save two creatures from damage-based board wipes or targeted red removal spells. In a pinch, it can be cast without targets just to trigger life gain or 'prowess' style effects.
Interaction examples
You are being attacked by two 2/2 creatures and you block with two 1/1 tokens. You cast Tandem Tactics targeting both tokens. They become 2/3 creatures, allowing them to survive the combat and destroy the attackers, while you gain 2 life.
You cast Tandem Tactics targeting one creature. In response, your opponent casts Swords to Plowshares on that same creature. The creature is exiled first. When Tandem Tactics tries to resolve, its only target is gone. The spell is countered by game rules, so you do not get the +1/+2 bonus and you do not gain the 2 life.
You cast Tandem Tactics targeting two different creatures. Your opponent responds by casting Path to Exile on one of them. The first creature is exiled. However, because Tandem Tactics still has one legal target remaining, the spell resolves. The second creature gets +1/+2 and you gain your 2 life.

- #1· Wizards of the Coast
You can cast Tandem Tactics with no targets. When it resolves, you’ll gain 2 life. However, if you cast Tandem Tactics with any targets and all of those targets are illegal as it tries to resolve, it won’t resolve and none of its effects will happen. You won’t gain 2 life in that case.
