Reweave

Does it refer to supertype (Land, enchantment, creature) or Subtype (eg. wizard, elf, Forest)?

Whan about legendary or snow supertypes... ? Same for Planeswalkers... What if I have Jace and tezzeret in deck or small jace and big jace...

Since there is errata regarding tribal instants i just guess it works only with subtypes, but what if I target land without any subtype?

Or it works with all types that card has (one at least)... Eg Creature targeted, first creature will enter battlefield no matter I targeted elf and wizard is revealed.

The current card types are artifact, creature, enchantment, instant, land, planeswalker, sorcery and tribal. That's what Reweave refers to. Supertypes like legendary or snow don't count, nor do card subtypes. It goes from creature to creature and from planeswalker to planeswalker.
