Yes you can.
A level 7 monster needs two tributes; you can tribute a level 5 monster but must also tribute a second monster.
A Level 8 monster needs two tributes, so you can tribute a Lv5 monster, but must also tribute a second monster too.
A Tribute Summon is the "Normal Summon" of Level 5 or higher monsters. To Normal Summon these cards, you must first Tribute monsters on your side of the field. To Tribute Summon a Level 5 or 6 monster, you must Tribute one monster. To Tribute Summon a Level 5-12 monster, you must Tribute two monsters.To Set a Level 5 or higher monster, you must still follow the same guidelines concerning Tributes as stated above.A Tribute Summon is treated as a Normal Summon (however, some monsters state specific ones, such as the Monarch series). Therefore, you can generally only Tribute Summon or Tribute Set once during each turn (it also counts towards your Normal Summon limit). It is also important to note that Tributing a monster is considered a Cost for a Tribute Summon or Tribute Set. Because it is a Cost, if the Tribute Summon is negated by a card effect, the Tributed monster does not return to the field.For more information regarding Tribute Summoning and Tribute Sets, click on the appropriate "Related Links" below.
No... a level 4 monster can be summoned without a tribute monster, but a level 5 and 6 needs 1 tribute monster and level 7 and so on needs 2 tribute monsters.
Taken from the Official English Rulebook: ...However, for Monsters that are Level 5 or higher, you must Tribute at least 1 monster you control before the Normal Summon. This is called a Tribute Summon. Monsters that are Level 5 or 6 require 1 Tribute and Monsters that are Level 7 or higher require 2 Tributes. Monsters that are Tributed are sent to the Graveyard and the "Tribute Monster" you are Summoning is played in face-up Attack position or face-down Defense position (a.k.a. a "Set").
You can set the monster you tributed for, but the tributed monster is sent to the graveyard
yes, only if it is a level 4 or lower monster. other cards like a legendary ocean that can reduce a monster's level by 1 can let you normal summon a level 5 water- type monster without a tribute.
No. You tribute one monster of any level to summon a lv 5 or 6 monster, and two monsters of any level to summon a lv7+ monster. Some monsters have additional requirements, three tributes for example. But the level of the tributed monster is rarely relevant.
It is Level 5, so one monster.
Well from 9-12 yes, but level 4 or lower monsters don't require a tribute so unless stated on the card they cannot.
It depends on the level. If it is 4 stars or under, then no. If it is 5-6 stars, then you need to tribute 1 monster. If it is 7-12 stars, you need to tribute 2 monsters. Many high level monsters cannot be tribute summoned though and will have their own summoning text.
Yes. To Special Summon a Level 7 Toon Monster, you must Tribute any two monsters on your side of the field. For Levels 5-6, you must Tribute one. For Levels 7 and above, you must Tribute two. High Level Toon Monsters follow the same guidelines as Tribute Summons. Note that it is considered a Special Summon, not a Tribute Summon.
