It rewards players who practice and know the cards theyre aiming for, but can be a little tricky without a defense plan
It also has loads of very cheap low value cards so flooding is pretty devastating
If, during a player's declare attackers step, a creature that player controls that's been goaded is tapped, is affected by a spell or ability that says it can't attack, or hasn't been under that player's control continuously since the turn began (and doesn't have haste), then it doesn't attack
If the spell or ability later returns the card to the battlefield, it will return as a new object with no relation to its previous existence
Nibelheim Aflame also works well with creatures with Deathtouch, since the Creature itself is dealing the damage to every other creature
While each of them have their own specialties, they all have plenty of synergy with one another out of the box
