Help understand Morgrul's Ragers card, please

I can't understand this description.

1. If I play this card, do I get a global rage (all friendly minions will gain rage)? It seems a very good deal for only 4 mana. But this doesn't seem to happen every time and I don't understand why.

2. If a Voidborn minion hit the opponent base, it gets rage, but this card must be in my deck and not on the battlefield, is that it?

The card summons 2 elite swarmers.
When holding the card in hand, before playing it, the card has a condition.
The condition is to have a voidborne minion damage the enemy tower.
If that condition is met, the card will gain a new atribbute.
The atribute is that the card also gives rage to all friendly minioms when played, besides the swarmers.
Without the condition, they are just 2 swarmers.

Oh, ok... so some Voidborne minion MUST have hit the master's base WHILE I'm holding the Morgrul's Ragers in my hand. When these 2 conditions are met, the card gains a new attribute: it will provide a global rage to all friendly minions, besides the 2 swarmers.

What a terrible card.

the cards with light up "golf" when there condition is met.

What a terrible card.

its actually a really good card IMO just gotta trigger the condition.

in team battle your ally can trigger the condition. colossus and rammer combo is great with morgruls ragers
