“Monarch” monsters are Level 5 or higher monsters with various effects that usually activate upon being Tribute Summoned.
Cosmic Cyclone allows you to get rid of the opponent’s back row.
Decks that are heavy in back row may give you some trouble: Floodgate Trap Hole and Paleozoic Canadia could put the Monarch you’ve just summoned in face-down Defense Position, making it an easy target for an attack, so preemptively getting rid of them would be ideal.
You can chain Cosmic Cyclone to Treacherous Trap Hole and target it in order to be able to utilize a second one since the Trap Card would end up banished as opposed to in the Graveyard.
Both Mithra and Dynaterium can be Special Summoned from your hand and then used to Tribute Summon a Monarch: Mithra Special Summons a Token on the opponent’s side of the field when she is Special Summoned by her effect, but she also allows you to Tribute Summon a monster during your Main Phase this turn, in addition to your Normal Summon/Set;
Dynaterium allows your opponent to Special Summon a monster from either player’s Graveyard, but it has to be Level 4 and at the beginning of the duel there will likely be nothing to Special Summon.
When Tribute Summoned, Thestalos forces your opponent to discard a random card from their hand and then, if it was a monster, your opponent also takes damage equal to that card’s Level x100.
Cards in hand are usually pretty limited: Thestalos might force a Fur Hire player with a Wiz, Sage Fur Hire to discard a Fur Hire card they could have used to negate one of your cards or just get rid of a monster that your opponent was going to Special Summon during the Battle Phase in case of an Amazoness matchup.
The damage caused by the effect is not particularly relevant, but it’s a nice addition that could even finish off your opponent.
Monarchs are pretty limited offensively when it comes to raw stats, having exactly 100 ATK less than Dyna, Hero Fur Hire, a monster that you will have to face a lot, so Zaborg with its Monster removal effect is pretty much necessary to play the deck competitively.
Zaborg can destroy a monster your opponent controls, regardless of the its position, which is great when you're facing Amazoness and you have destroy Amazoness Queen or just to get rid of a Wiz, Sage Fur Hire in Defense Position.
Granmarg can destroy a set card on the field: ideally this would be a Spell or Trap Card that your opponent controls.
Remember that this effect is mandatory, so wait until you summon him before setting a card, if your opponent has no set cards on his of the field.
Angmarl the Fiendish Monarch
|Angmarl can add a Spell Card from your deck to your hand by banishing another copy of that Spell from your Graveyard.|
|Treeborn Frog has synergy with Enemy Controller: you can chain the Quick-Play Spell to its effect during the Standby Phase to take control of one of your opponent’s monsters and then get it back again.|
|Sphere Kuriboh and the regular Kuriboh work pretty well in a Cyberstyle deck: they offer protection and they allow you to generally take how much damage you want for Cyberstyle.|
|Being able to Tribute Summon one of your Monarchs using an opponent's monster is great, but it forces you to skip the Battle Phase and a Wiz could mess up this card quite easily.|
|Quick backrow “removal” before you summon Zaborg or Thestalos|
|Usual way of dealing with Fur Hires or slowing down almost any kind of deck.|
