I like this for equipment decks
It is not recommended to revive an "Ojama Knight" or and "Ojama King" as to include effective Synchro Summoning in the Deck, you do not have space for effective Fusion Summoning also, as well as the fact that "Ojama Knight" is Level 5 and "Ojama King" is Level 6, and as all Level 9 or higher Synchro Monsters require 2 or more non-Tuner materials, this means that you cannot Synchro Summon with the monster you revive with "Debris Dragon"
I find it difficult figure out how much they are worth and if so how much
If Magicat is sent to the graveyard for the synchro summon of a spellcaster monster, you can put any spell card from your graveyard to the top of the deck meaning you can use it all over again next turn
Rather, its a prime example of how Wizards tends to push new card types and mechanics early in an effort to encourage players to try them out while also seeking the tipping point between unplayable and too good. This is the same principle that lead to the creation of ban-worthy cards like Smugglers Copter
A subpar card for what otherwise would have been one of the most loved planes of all time
