Magma Sliver turns your entire Sliver board into a collective firebreathing engine — every Sliver can pour mana into any attack, threatening lethal damage out of nowhere. The cost is steep at five mana, but in a The First Sliver cascade shell that problem mostly solves itself.

The First Sliver
The First Sliver cascades into Magma Sliver and then keeps cascading down the chain, meaning you often land this and additional pump pieces in the same turn — at that point every attacker is threatening to one-shot someone at the table.

Commander is where Magma Sliver actually lives — the Sliver tribe is deep enough here to make the firebreathing ability genuinely threatening, and the five-mana cost is acceptable in a 40-life format where the game goes long enough to use it. Legacy and Vintage are both legal but offer nothing for it: competitive Sliver builds in those formats lean on speed and disruption, and a five-drop that requires more mana to do anything is simply too slow. Magma Sliver is a Commander card through and through.
