Good card, yes it would seem to be a cycle of alliances between two guilds. This is Selesnya-Simic, Bond of Discipline was Orzhov-Azorius. My guesses for the other three are:
[Izzet-Dimir] Bond of Understanding - XU
Sorcery
Scry X. Then each player puts the top X cards of their library into their graveyard, then you may return an instant or sorcery card with converted mana cost X or less from your graveyard to your hand.
Exile Bond of Understanding.
--- We agree that knowledge is power, we just don't agree on how to share it.
[Boros-Gruul] Bond of Aggression - 5R
Sorcery
Creatures you control get double strike and trample until end of turn.
--- We agree we need to fight, we may not agree when to stop.
[Golgari-Rakdos] Bond of Sacrifice - 4B
Sorcery
Sacrifice any number of creatures. Each opponent sacrifices that many creatures and you gain that much life.
--- We agree that life is sacrifice, but you seem to take more pleasure in it.
