By training it in the Monster acadmey
No, the requirements to summon a syncro monster are printed on the card. Example: Junk Warrior requires Junk Syncron and 1 level 2 monster or 2 level 1 monsters.
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.
Unless they are monsters that are special summon only, level 7+ monsters require 2 tributes.
A level 7 monster needs two tributes; you can tribute a level 5 monster but must also tribute a second monster.
A level 7 monster needs two tributes, so you can tribute a level 6 monster but must also tribute a second monster.
A level 8 monster needs two tributes, so you can tribute a level 6 monster but must also tribute a second monster.
Level 7
You will have to reach level 10 in order for your monster to level. The next evolution is on level 20.
You only need 2, like any other tribute monster that's level is 7+
A Level 8 monster needs two tributes, so you can tribute a Lv5 monster, but must also tribute a second monster too.
If you have a level one monster academy, you will be able to upgrade all of your monsters to level two. But to upgrade your monsters to level three, you must first upgrade your monster academy to level two. Then, once you have upgraded your monsters to level three, you must upgrade your monster academy to level three. I.e, if you have a level two monster academy and your pokeys are upgraded to level three, if you want to upgrade your pokeys to level four, you must upgrade your monster academy to level three.
